Just wondering what cold air intake people are liking on their ST so far? I want warranty approved first and foremost, and sound/performance second. And yes I know the performance isn't a big gain, I'm just looking for the little things to do.

For warranty friendly your options are the Ford Racing Intake, and the Mountune low loss crossover tube intake with or without the air filter. Technically they may have to be installed by the dealer to maintain the Ford Racing warranty however.

I'm perfectly happy with this combination on my own ST although I may have installed the parts on my own.

Aftermarket CAI's are worthless, mythbusted nonsense till you swap out to a bigger turbocharger. I've been dyno'ing/tuning all kinds of cars and unlike many tuning, speed shops, I was never in it for just the $$ like 95% of them are. They SAY and post numbers that show huge gains with upgraded CAI's, but that's just not possible. They alter the tune, that's it, to make it LOOK like the CAI is making more pwr. It deceptive business practices. Also, proper dyno's are done "hood closed". We don't drive down the road with our hoods open, so why dyno that way? It just creates false numbers.

Sure, with the hood wide open, and fans blowing a 20 mph breeze on to the engine, false air flow and false cooling occurs. When you vehicle is moving, the hot air escapes through the the gap between hood and windshield, and through the little vents on the plastic dust shield that surrounds the wiper blades and covers the hood area at the windshield. With a hood open, heat just goes straight up and out, thus creating that false cooling, and generating over inflated dyno numbers. I've been dynoing cars like I said, over 27 yrs. I know what works and what does not a dhow dyno's are done in Europe and Austrailia, all hood closed.

About the only thing you can do that won't void your power train is the K&N drop-in replacement, muffler swap/axle back or the Ford Racing tune. Be aware too, the Ford tune reduces power train warranty from 5/60k to 3/36k. The rest of any mods, you either wait for warranty expiration, or you have to pay to play, and lastly, just wait for the forthcoming, (premium mustang GT level expensive) RS. After market CAI and a cat back might, MIGHT net you a whopping 5-7 hp total. To me, not worth it. If you want some cheap sound change, play with the pipes out back and resonator.

And suss6052 is correct. Ford would have to install. That snorkel ford racing piece that goes down to the grille area to catch fresh air is better than just the opening that sits behind hot metal, in no airflow. Steeda, has been contracted with Ford for over 20 yrs, they make some of the best parts. Ford Engineers have given authorization to Steeda to make/design parts. They have a nice simple snorkel too. And no, the bumper does not have to come off, just use some enginuity.


Plus, fords new tune is great but, it adds 90 lb-ft of tq at a small early point in the rpm, then falls off to 20 lb-ft by 3900 rpm. The car will feel weak kneed above 4500 rpm. And tq steer will be a problem.

Hi guys I'm in Australia and we don't have much options. After much research and checking my bank balance I have decided to drill extra holes in the bottom of the original air box to suck extra air from the bottom. I have had much success with this in the past. (A FSWerks CAI is $350 (USA) plus freight) I have ordered a BMC high flow Air filter and then the car is going to be remapped at a Tune specialist for $1250.. All up close to 1450. The technician stated that if I were to change exhaust I may need to look to update my clutch as the ECO boost motor has unbelievable result in increasing torque.. He claims Kw should be up but not as much as % torque and fuel economy will increase.. Should be completed within 4 weeks I will give you the result.. Cheers!

There really is no warranty approved cold air intake. Since it is a bolt on item so if you did have a warranty issue say with a check engine light you could go back the stock air box before you take ur car to a dealer for repair.

I decided to go with the roush intake, it does use the stock air box bottom and a larger diameter turbo tube.

Worth reading; Magnuson Moss Warranty Act: USCODE Title 15, Chapter 50. section-2301-2312. This protects us car nuts. K&N filters has a card that comes with the filter, for you to use, if service is denied because of the filter. MOD ON!!!!!!!!
