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.
$239.95
