    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.

    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.

    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?

    prouddad

    • 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!

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

    sh46

    • 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.

    does this CAI come with a carb sticker? since CA ask for one when doing smog

    Vlad

    • This Roush Cold Air Intake is CARB legal under EO D-418-14 for the 05-07 model years. The intake would also come with all documentation needed to show that for smog testing.

    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.

    AdrianS

    • The Roush Cold Air Intake would have the venturi tube which can be removed to allow more airflow into the car. This would require a tune with the tube removed and will gain much more power than when the tube was installed.

      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.

      Sort of happy

      It seems to be a very well-made product although if you read the reviews everybody has the same problem I had screw holes don't lineup and clamps are too small you would think that Roche would fix this problem other than that I am very well pleased with this product and would buy it again hopefully they get the bugs out of it

      WOW!!

      Definitely the best performance mod I have ever done to my car wow what a difference. Although I may be the only one who actually lost gas mileage but it was totally worth it I didn't buy this card save gas money. But like everyone else I have to mention the clamps... What were you thinking about Roush did you even try to put this thing together before you boxed it up and started selling it?

      Looks great, fits perfect, airflow TBD

      Got this CAI and installed it right away with the provided insert that doesn’t require a tune. I also ordered a tuner and a twin 62 GMS throttlebody. Waiting on the tuner so I can remove the insert and really open up the airways. So far so good, easy install, perfect fit, looks good. Just make sure to 2 bigger hose clamps like everyone else has said.

      Worth every dime

      This air intake will grant you instant power that you sure will notice right off the bat, even without a tune! Its great, the only thing is the clamps they sent (64mm x 2) dont fit, but if you find any at some stores around town they will fit (yes the 64mm). Roush must have made them just a tad small. Also the sound this makes is very very nice!

      I give credit where credit is due, I bought a roush cold air intake from American muscle and it’s the best 319.00 dollars I ever spent!! Very easy to install, very large easy to read instructions. And the extra power was amazing!!! Louder exhaust and sounds very mean now. After installation I took it up the road and with a smile a mile wide, it even gave me cold chills! And better mileage too. And customer service was great! I’m very very pleased!
