This unit is a 2 piece unit, and resembles the focussport CAI very closely... it comes in variety of colors... but it seems walter has updated and changed his website again, and is not listing it... but you can maybe get it from him still at or a used one.

$180.00 - 10 - 11hp

F2 Focus:

F2 Cold Air Intake Duratec is back and will be available by December 15, 2007! You can preorder it if you like to make sure you are on the list before they are sold out. We bring back our original design which yielded 10whp on the dyno! With the addition of K&N air filter or outerwares as an filter option this is by far the best priced intake in the market for the Duratec Focus. The intake will only be available in powdercoat black finish.

$135.00 - 10hp

Your choice of 45mm Straight ITB's or 45mm Tapered to 50mm ITB's. Includes our Standard Foam Filters as well. PRICE: $1,199.00


These prices are not exact, i searched and when i came across a price i copied it, has pretty much almost all of these intakes for good prices, but you can purchase from where ever you want, if you find a good price.


*Cold Air Intake Pros:
-Cooler air brought in means denser air which = more power
-Bling Factor, having an intake tube snake down into the bay is liked by some
-Limited Heat soak

*Cold Air Intake Cons:
-Chance of Hydrolock (low, but its still there)
-Price, typically more expensive


*Short Ram Intake Pros:
-No chance of Hydrolock
-Bling Factor, having a big air filter in eyes view is liked by some
-Typically cheaper

*Short Ram Intake Cons:
-Very absorbent to heat soak(this is where the air filter sucks in warm air from the engine bay, thus loosing power)
-Less horsepower/torque


*Pros for ITB's (cosworth)
-Most N/A hp/tq available
-Huge Bling factory (everyone usually loves ITB's)
-Quality, Cosworth is 2nd to none

*Cons for ITB's(cosworth)
-Makes N20 abit harder
-Makes S/C and Turbo near impossible
-Makes tuning alot longer/harder

Air Filters for Your CAI/SRI:

With our CAI/SRI's there are basically 2 options, the ITG with the focussport, or the K&N, all of the other intakes use a K&N or rebadged K&N filter, you can purchase the ITG or a Cone style K&N seperately, you can easily find the K&N cones, but focussport does sell the ITG "cone" by itself.


About ITG Air Filters
The Best Air Filters Ever Made, Period.

ITG's current range is the product of almost 19 years of constantly striving for the best designs, made from the best materials with the best manufacturing methods. Whether you're racing, rallying, cruising or shopping, you can be sure nobody makes a better filter.

The best proving ground for any performance product has always been motorsport, that's why top teams from WRC/F2 Rally Cars to Super Touring and Formula 1, make ITG their first choice in air filtration.


The technology of 'Reticulated Polyester Foam' allows itg greater flexibility in design and performance than paper or cotton gauze style filters. itg was probably the first company to manufacture a truly durable, high performance foam-based production air filter.

Why foam? Because, compared to paper or other filter technologies, reticulated polyester foam achieves optimum performance against three key criteria:

1. Maximum Air Flow - the filters ability to allow air to pass through without causing a large pressure-drop.

2. Cleaning Efficiency - the capacity of a filter to arrest a high proportion of the dust carried in the air, whilst feeding the engine clean air.

3. Dust Load-up Tolerance - the capability to absorb a large amount of dust, without reducing air flow capacity.

With the unique Tri-Foam System, which uses various thicknesses of finer or coarser foams, these factors can be varied for different applications.

Tri-foam gives us the flexibility to produce air filters to exact specifications and, where high flow rates are possible, we can tailor filters to arrest even the slightest dust traces.

What's more, because we use the very latest adhesive technologies to bond the foam layers, itg filter assemblies are totally resistant to water, fumes, oils and fuels - including the exotic brews used in racing.

From K&

We believe the primary function of an air filter is to deliver both high airflow and superior dirt protection. We design our air filters to provide minimum restriction allowing high airflow into an engine. In the vast majority of cases increased airflow will increase engine performance measured by horsepower and throttle response (torque). The performance benefits of maximum airflow are clear, compelling and well documented. That is why so many professional racers are willing to run expensive vehicles with no air filter, as opposed to installing a disposable air filter. They are seeking the additional horsepower and throttle response needed to win the race.

We design our air filters to provide superior filtration of the contaminants that can harm your engine while maximizing the airflow characteristics of the filter in question. The ability of an air filter to protect your engine is generally measured in accordance with testing procedure ISO 5011. We subject a sample of our filter designs to this test procedure using Coarse Test Dust, which includes particles ranging in size from less than 5.5 microns to 176 microns. As a point of reference, a human hair is approximately 50 microns in diameter. The result of the above test procedure is a specific air filtration efficiency number. This efficiency number represents the percentage of test dust retained by the filter and thereby kept out of an engine. Our goal is to design our air filters to achieve maximum airflow while targeting overall filtration efficiency at 98%.

Because no two air filters are alike, the specific airflow and overall filtration efficiency will vary depending on the filter in question. However, you can rest assured that each air filter we sell, has been designed to achieve high air flow while providing superior filtration.

Both air flow and dirt protection are critical to engine performance. For this reason a consumer should always evaluate an air filter based on both its filtration efficiency and air flow capabilities. It is very easy to design an air filter that exhibits high airflow simply by reducing its filtration to unacceptable levels. As the “look” of a K&N air filter has become popular, many companies have begun offering products that copy that “look.” While imitation is said to be the sincerest form of flattery, our own testing has shown that many of these look-alike products do not provide a safe level of engine protection.

There are few areas more confusing than identifying dirt retention requirements when it comes to air filters. Most vehicle owner’s manuals remain silent on the point. In fact, few air filter manufacturers publish any information as to the filtration efficiency of their filters. This stands in marked contrast to oil and fuel filters where there is a relatively large amount of information regarding filtration requirements and capabilities. Studies have shown most engine wear is caused by particles 10 to 20 microns in size. K&N air filters, like most quality disposable air filters, provide excellent filtration of these particles.

To ensure our air filters provide a high level of dirt protection, we regularly test our air filter designs using the testing procedure described above. Those tests demonstrate K&N air filters generally achieve overall filtration efficiency in the range of 97% - 98%, while some of our air filter designs have achieved levels as high as 99%. The fact that our air filters at times reach overall filtration efficiencies as high as 99% while maintaining high airflow is a testament to the quality and capabilities of our oil impregnated cotton air filter medium.

On occasion we see “new” air filter media’s developed and sold under the premise they provide increased levels of dirt filtration. More often than not, as opposed to quoting specific efficiency numbers, this “increased protection” is described as increased dirt retention capacity, meaning the filter can hold more dirt before requiring replacement. Remember, K&N air filters have always provided a service life in excess of disposable filters and then only require cleaning and oiling for re-use.

We encourage customers to do their homework and be aware of the filtration capabilities of an air filter before they buy. Our own testing has revealed wide differences in filtering capabilities. We were surprised to see some disposable paper air filters with an overall filtration efficiency as low as 93%. We hope we have provided enough information to ensure consumers know what they are getting when they buy a K&N air filter.

those are just 2 quotes and alittle information on the 2 types of filters.

i hope this helps with any new people in their decision for the intake purchase for their car.


*2008* Ford Focus Intake's

[B] Well, with the growing number of Duratec performance members, owning and bringing in the 08 for Performance Mods, usually everyone typically starts with an Intake.
As of Right now, there are very limited options, and I will go through them below:


---K&N Replacement Filter---

Often these Go also by Drop-In filters, as they require NO modification to be installed.
2008 has an advantage over the earlier Model duratecs, as the earlier models have a 100k non-serviceable filter from the factory.
Wheres in 2008, they have a serviceable filter, which allows it to be replaced by a "drop-in" filter

K&N’s replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. We make over 1,200 different replacement air filters for virtually every vehicle on the road. These filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most vehicles you simply remove the disposable air filter and replace it with a K&N. See applicable instruction sheet for details. Our stock replacement air filters for street vehicles are covered by our famous K&N Million-Mile Limited Warranty™ and will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.

---K&N 69 Series Typhoon Kit---

Built for performance and show, the Typhoon™ Air Intake System is a free-flowing mandrel-bent aluminum tube induction system designed to fit many sport compact performance vehicles. Typhoon intakes come in one of three designs; cold air intakes (CA), short ram intakes (SR), or complete cold air (CCA) intakes which can be configured as either a cold air intake or a short ram intake. Some Typhoon's have high quality finish options including polished aluminum (part ends with TP), powder coated blue (part ends in TB), powder coated red (part ends in TR), and powder coated silver (ends in TS) among others. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction allowing more air flow to your engine. More air means more usable power and acceleration throughout the engine's RPM range.

---Steeda Short Ram Intake---

Steeda calls it a Cold Air Intake on their website, but infact, it really is a short ram intake.

Steeda's new high flow air intake for the 2008 2.0L Ford Focus is 2 intakes in one all inclusive kit!

Our high flow cold air intake includes an insert allowing you to use it as a direct bolt on intake kit with no tuning required, or remove the insert to for even more airflow and combine it with a custom tune for the most powerful kit on the market for your Focus.

Steeda's cold air intake kit is also designed to use your stock air induction system, helping to take in cooler outside air!

Steeda's high flow intake also features a stainless steel heat shield and high flow cone style air filter for great airflow. Low intake air inlet temperatures can be accomplished with the heat shield and a provision to re-use your factory Ram air. Improved gas mileage will also be noticed!

We got an easy 7hp and 12ft/lbs of torque in mid range RPM's with peaks around 6hp and 5ft/lbs with the insert in place. More to be had with no insert and custom tuning.


To read Specifics and information directly related to the filters these 2 use, please check out

Next is the Fuel Economy thread:

All information was taken from:

Fuel Economy.Gov

Well with a certain and obvious (with gas prices) reason to talk about economy, I have decided to help out, and make a more singular source for the economy enthusiasts.

or MPG-Mongolars. lol

So here it goes!


All the information Sourced on this Post is from, but feel free to add information, remember this is a discussion thread on Fuel economy, so please add all that you can!

Next I will List some helpful tips, on how to obtain and increase fuel mileage!

Drive Sensibly
Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.
Fuel Economy Benefit: 5-33%
Equivalent Gasoline Savings: $0.20-$1.31/gallon

Observe the Speed Limit
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph.
You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.30 per gallon for gas.
Observing the speed limit is also safer.
Fuel Economy Benefit: 7-23%
Equivalent Gasoline Savings: $0.28-$0.91/gallon

Remove Excess Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
Fuel Economy Benefit: 1-2%/100 lbs
Equivalent Gasoline Savings: $0.04-$0.08/gallon

Avoid Excessive Idling
Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

Use Cruise Control
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

Use Overdrive Gears
When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

Cost savings are based on an assumed fuel price of $3.96/gallon.

Next is a quick excerpt that can easily help in day to day life!

Combining errands into one trip saves you time and money. Several short trips taken from a cold start can use twice as much fuel as a longer multipurpose trip covering the same distance when the engine is warm. Trip planning ensures that traveling is done when the engine is warmed-up and efficient.
With a little planning, you can avoid retracing your route and reduce the distance you travel as well. You'll not only save fuel, but also reduce wear and tear on your car.

If you can stagger your work hours to avoid peak rush hours, you'll spend less time sitting in traffic and consume less fuel.
If you own more than one vehicle, drive the one that gets the best gas mileage whenever possible.
Consider telecommuting (working from home) if your employer permits it.
If possible, take advantage of carpools and ride-share programs. You can cut your weekly fuel costs in half and save wear on your car if you take turns driving with other commuters. Many urban areas allow vehicles with multiple passengers to use special High Occupancy Vehicle (HOV) lanes.
Consider using public transit if it is available and convenient for you. The American Public Transit Transportation Association has links to information about public transportation in your state.

A roof rack or carrier provides additional cargo space and may allow you to meet your needs with a smaller car. However, a loaded roof rack can decrease your fuel economy by 5 percent. Reduce aerodynamic drag and improve your fuel economy by placing items inside the trunk whenever possible.
Avoid carrying unneeded items, especially heavy ones. An extra 100 lbs in the trunk reduces a typical car's fuel economy by 1-2 percent.

And heres the section that we all love! Maintaining your vehicle properly!

Keep Your Engine Properly Tuned
Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent, though results vary based on the kind of repair and how well it is done.
Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.
Fuel Economy Benefit: 4%
Equivalent Gasoline Savings: $0.16/gallon

Check & Replace Air Filters Regularly
Exempt except for 08+
Replacing a clogged air filter can improve your car's gas mileage by as much as 10 percent. Your car's air filter keeps impurities from damaging the inside of your engine. Not only will replacing a dirty air filter save gas, it will protect your engine.
Fuel Economy Benefit: up to 10%
Equivalent Gasoline Savings: up to $0.40/gallon

Keep Tires Properly Inflated

You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.

Fuel Economy Benefit: up to 3%
Equivalent Gasoline Savings: up to $0.12/gallon

Use the Recommended Grade of Motor Oil
You can improve your gas mileage by 1-2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1-2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1-1.5 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.
Fuel Economy Benefit: 1-2%
Equivalent Gasoline Savings: $0.04-$0.08/gallon

Note: Cost savings are based on an assumed fuel price of $3.96/gallon.

Also! just because People advertise MPG this and MPG that! here are a couple quick facts about that marketing:

EPA tests are designed reflect "typical" driving conditions and driver behavior, but several factors can affect MPG significantly:
• How & Where You Drive
• Vehicle Condition & Maintenance
• Fuel Variations
• Vehicle Variations
• Engine Break-In
Therefore, the EPA ratings are a useful tool for comparing the fuel economies of different vehicles but may not accurately predict the average MPG you will get.
To find out what you can do to improve the fuel economy of your car, see Driving More Efficiently and Keeping Your Car in Shape.

and a quick question that I'm sure is on a few people's minds.

Question: What's up, and down, with gasoline prices lately?

EIA analysis of the petroleum market points to the cost of crude oil as the main contributor to the large run up in the first half of 2008 and the recent decline in retail gasoline prices.
The cost of crude oil accounts for about 74% of the gasoline pump price (see graphic on gasoline price components). The cost of crude oil for U.S. refiners reached a record high in early summer 2008 (as did retail gasoline prices) due mainly to high worldwide oil demand relative to supply. Other contributing factors included political events and conflicts in some major oil producing regions, and other factors.
EIA believes that the high prices for petroleum products and relatively weak economic conditions in the U.S. and other countries has helped to reduce demand and prices for crude oil. This has contributed to the recent decline in crude oil and retail gasoline prices.

I hope this clears up some questions, But I mainly did this to help center all of the Mileage and fuel threads to one local area, so that way we don't all have to go through a lot of different threads!

Good Luck on saving fuel, and keep posting!
