    Increase Horsepower and Torque. The Roush Performance Mustang Cold Air Intake kit replaces your stock GT Mustangs restrictive factory air box and paper filter with a high flow filter assembly and intake tube for an increase in horsepower and torque while improving throttle response and fuel mileage.

    No Tune Required. Unlike other Cold Air Intakes on the market for the 2005-2009 GT Mustangs the Roush CAI does not require a computer re-tune. The engineers at Roush Performance really did their homework to improve your pony's power using the factory tune.

    Reusable Filter. Roush designed the high flow air filter to be reusable. So no need to go out and buy a new filter every few thousand miles. Just clean the filter, re-oil it, save money, and go!

    Superior Quality. Roush manufactures the airbox tray and tube in this CAI kit from high quality thermoplastic materials for superior structural stability, and durability. And the kit comes complete with a custom high-flow ROUSH air filter with clamp, MAF tube, Airbox tray with installed EPDM foam hood seal, and the necessary Mounting hardware.

    Not CARB Certified. This Roush Performance Cold Air Intake is not CARB certified, therefore it is not legal for use in California or other states adopting California emission standards. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

    Application. This Roush Performance Cold Air Intake is specifically designed for the 2005 to 2009 GT Mustangs and does not require a new computer tune.

    5 Top Rated Questions

    Can you tune a Roush cold air intake? I have just installed a Roush cold air and it came with an insert to restrict air flow so no tune required. When I tried it without the insert (roush says thats for off road or racing in the instructions) it ran really bad. I mean really really bad and stalled. Yet with the restricted insert it runs like a top. Is there any tune for this cold air intake and will it make my car go faster?

    • Absolutely! When you run this Roush CAI with the insert, it allows the kit to be installed with the proper calibration so there is no tuning required. With the insert removed, you're removing the necessary calibration and can cause you car to run as you described above. If you want to run this CAI without the insert, that is by far the best option in regards to increased power and there is a tune available. Our Bama team can create a custom tune for your Roush CAI, giving you max performance for this mod and any others you have or plan to do. If you have any additional questions, definitely give us a call and we'd be happy to help!

    Will this fit on a 62mm throttle body?

    do you need to use a higher octane gas with the roush cai if not tuned?

    • Absolutely not. This specific intake is designed to run without computer tuning required...though I HIGHLY recommend getting one for the performance/fuel economy enhancements. Regardless, you may run 87 Octane fuel if you're on your factory tune...that's what the factory tuned it to run on minimally. Run higher if you like, though you will likely not see any difference until it's high-mileage.

    Hello, Is the restrictor available separately? I bought this kit quite a few years back fitted it and the car developed a terrible misfire. Put the original airbox back in and was fine. I didn't know at the time it needed a restrictor and did not get one with the kit and has just been sitting on the shelf ever since.

    • At this time we do not offer any form of restrictor for the Roush Cold Air Intake.

    Is this California legal?

    • This Roush product is 50 state legal for the 2005-2007 GT Mustangs and would be legal to run in California if you have that year Mustang with EO# D-418-14. However, the EO # has not been updated to have this 50 state legal for the 2008-2009 Mustang GTs. If you have a 2008-2009 Mustang GT, this would be legal to run in the state of California, unfortunately.

    Okay I have this roush cold air intake and just installing it makes a little power I’ll admit. However. I noticed a insert in it that necks the intake way down. And if I remove it my car sounds cammed (really awesome). I know it’s bad for it so I don’t run it or show off with it. Just wondering if I were to remove it and tune it right what would the hp gain be for that? If anyone’s ever tried. 1 answer

      Worth every dollar spent.

      Easy installation, buy two 70mm clamps before you start to avoid any frustration. Performance gains are noticeable, gas mileage increase appear to be 2-3 mpg under normal city and highway driving, looks great, sounds great! Have not removed flow reducer yet, can't wait to do that and give it a tune.

      Very Good Build Quality, NEEDS Revision!

      So the Build Quality of all the parts is very good, the inside of the intake pipes is a polished finish, it feels like wet glass to the touch. However there is 1 Problem with this kit, Based on older pictures, i can see that the "Hump Hose" used to be thinner walled than the revised one that is now in this kit, as such, the two #64 clamps do not fit, PERIOD! Seeking 2 replacements that are slightly larger is required. The #64 clamps are literally 0.5-1mm too small to even get threaded in after wrapping them onto the thicker hump hose in these newer kits..

      Great build quality and sound

      Great product, looks sweet under the hood and sounds great. With a Bama tune and the insert removed from the intake, it's a really good first step, as the car becomes a bit more aggressive and has way better throttle response. Just like everyone else, I just had two clamps that were smaller than what was necessary but those can be purchased at any hardware store. It's really straightforward to install and the instructions where quite easy to follow. Thumbs up and I would definitely recommend it.

      Roush Cold air intake.

      After trying a cheaper after market cold air intake I returned it and ordered this one. Fit perfectly in stock mounts. Huge improvement in throttle response! Runs much smoother and the sound under the hood combined with exhaust tone from Flow masters is outstanding.

      Roush cai

      Pros: sound improvement. 2 mpg. Increased torque 2k-4K rpm. Looks great. Easy install. No check engine light. Cons: It “evens out my torque” which may be a good thing for some folks...but I miss that neck jerk’n at 4K rpm. Very satisfied!

      Roush Cold Air Intake for '05 GT

      Simple installation with noticeable improvement in both acceleration and engine sound. Excellent product and would have added fifth star but needed to purchase two number 72 hose clamps to finish installation. Roush provides two number 64 clamps which are too small. I knew this from reading several product reviews and can't understand why they don't address it.

      Roush can and should do much better

      Would have installed super easy and quickly if the two clamps on the bubble coupler weren't too small and had to make a run to the hardware store to get a pair of #72 clamps. It comes with (2) #64 clamps that are *supposed* to go on the bubble coupler (filter side), and (2) #72 clamps that go on the oval coupler (TB side). The #72 are a perfect fit for the bubble coupler, but alas when you put the #64 clamps on it is IMPOSSIBLE to get them to tighten! I tried getting one groove on the worm and even lubed up the coupler but it just wasn't going to go. The other annoying part was installing the filter adapter to the housing was a pain, because the tolerances of the holes on the housing were way off and I had play around with it for a bit to get it to fit. Roush can and should do better than this (in fact, why isn't this pre-installed anyway??)

      Great simple mod upgrade

      Overall 4.5 stars and great product. This CAI was simple to install with the easy to follow instructions, taking about an hour. Similar to most reviews found the provided size 64 hose clamps inadequate for connecting the filter portion to the air tube. Took a quick measurement and the extra length required was about 13mm, and therefore purchased size 72 from hardware store to complete installation without any problem. Rough should really replace the size 64 clamps with 72 to reduce customer complaints. Noticed increased throttle response especially when accelerating hard throughout RPM range. I do a lot of local, stop and go, driving and have only observed less than a mile increase in fuel economy; however, when driving steady, less stoppage in the city, the fuel economy increases by nearly two miles. Still need to assess the highway driving but anticipate an increase there also. Exspect even more performance after an upgraded tune with restriction insert removed.
