      Description

      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.

        Roush Cold air intake

        Just finished installing. Was quite easy. Fit and finish was very good. I can’t comment on the performance aspect of it at this time because I haven’t driven the car.

        Would have expected it to be perfect for the money

        Everything went well with the install until the point at which I had to insert the MAP sensor back into the tube slot. The MAP sensor would only part way. When I removed the MAP I could clearly see the slot on the insert was at least 1/4 inch smaller than the main airflow tube. I insured the insert was fully engaged into the main tube and insured alignment. Unfortunate the only way to fix the issue was to file the slot in the insert larger until it accepted the MAP fully. Once that additional work was completed everything else went fine. Would have given in 5 stars but with the ROUSH name would have expected a perfect fit.

        Roush CAI

        Arrived very fast (within 40 hours of purchase) it got here and install was quick and easy simply following the included directions. Took it out for a drive and it revs out so much faster now my 70 and above no longer feels sluggish I can’t wait to keep upgrading! Would highly recommend

        Works great

        The Roush intake works great with my 08 mustang GT. It gives it a very guttural roar once you hit the higher RPMs. It sounds great!

        My Mustang can breathe now!

        Watched the install video here at AM and had the old air intake out and the new Roush CAI installed in about an hour. Had seen the reviews about the two #68 clamps being too small, but my kit came with four #72 clamps, so Roush appears to have fixed that issue. Install was smooth, only discrepancy was the New screws for the air flow sensor weren’t the same size as the free bit in the kit. No problem because the bit I had out to remove the air flow sensor worked. After installing the engine runs smooth and the growl through the Borla pipes is a little richer. Subjectively there’s a little more pep during acceleration and feels like it’s just breathing better. Don’t know about improving fuel economy yet. Very good upgrade!

      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!

      Is the street legal in Massachusetts? I have a 2008 GT. If it is not legal will it still work?

      • That will depend on your state and their emission laws. Unfortunately it can vary so we recommend checking with your state ordinances or a local shop.

      Is there any way you could buy the mass air flow tube insert needed to use it without a tune lost it and now need it

      • Unfortunately the mass air flow tube insert is not currently sold separately from this intake kit. We would recommend reaching out to Roush directly.

      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.

      I'm adding a Roush CAI with the sleeve in, BBK shorty tuned headers, and a Flowmax high-flow catted H-pipe at the same time to a 2007 Mustang GT 4.6L. Each is supposed to work individually without a tune. Should I consider a tune given I'm adding all three together? I'm mainly interested in not damaging the engine. 1 answer
