Increase Horsepower and Torque.

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.

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.

More HP with a tune? I'm looking at CAIs for my 2008 gt and the roush stood out because it didn't need a computer tune. I'm wondering though. Will I get more horse power from a CAI that requires a computer tune then one that doesn't require a tune?

JoeVfx

  • It's hard to say exactly how much horsepower just a CAI will give you, but from an average just the ROUSH CAI with the restrictor tube in place and not tuned with net you maybe 5+ HP. With the restrictor tube removed and tuned, you can gain up to 35+ HP. I did this same exact upgrade and the difference was night and day and worth every penny.

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!

How much horsepower it make?

Efrain123

  • The Roush Cold Air Intake by itself will not do much. If you pair it up with a Bama X4/SF4 Power Flash Tuner w/ 2 Custom Tunes Item #101200G05 (http://www.americanmuscle.com/x4-custom-tuner-0510gt.html) and you will see gains of up to 30hp across the power curve!

Question Resolved

what is an insert for the cold air intake

rabbit

  • Certain intakes will have what is called a "Venturi tube" or an "Intake insert" that can be inserted to so the intake can be used without needing a retune. When the Venturi Tube is removed it will allow for a lot more air to come through the intake but will require the car to be tuned to compensate for all of the new air. The Roush Cold Air Intake does not come with one of these removable inserts, it was designed to be used without a retune.

Question Resolved

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.

  • If you would like to modify it to make it work the way you want to you can, however the Roush Cold Air Intake (05-09 GT) is designed to be used as one piece.

    Quality Product, Quality Performance

    I'm an older fellow. My Mustang is one of my prize possessions. I keep it covered, in the garage when I'm not driving it. I've been adding various items and parts to improve appearance and performance to this beauty that I bought four months ago with only 2700 miles on it. It still looks and smelled new! I selected the Roush CAI because of the trusted name. Installation went well using the instructions in the box. I did get hung up removing the breather tube because the plastic end green tabs have to be pressed in a specific way and I didn't get it at first. I also did not install the Tube Insert which is mandatory in California and allows for the no tune installation. I got a computer tune and installed without the Tube Insert. My '08 now sounds and moves faster. I'm doing 0 to 60 in just under five with a street tune. Roush and BAMA do it again.

    No problems, No hassle.

    I had been looking around on several websites trying to find the most affordable way to gain some power on my 07 GT. After reading about all of the Mass Air Flow sensor issues on some other CAI's, I decided to raise my budget a little and go for the legendary ROUSH. It was definitely worth the extra money. This cold air intake went on with almost no thought, and I immediately saw gains in power. And I can't forget about that beautiful sound! The intake growls like never before. I definitely recommend this product, and I will be back for more!

    She's breathing much better!

    Received my order from American Muscle about a day after ordering (As usual :) I live in northern NJ). Literally swapped my factory airbox out, and the new CAI in on my lunch break. Instructions are very clear and the customer submitted ones helped tremendously, as well as they are in color and very detailed. Car is running great and is definitely a lot more responsive, not to mention it looks great. I did not use a tune on mine, just used the supplied restrictor for now. May tune it in the future, but its nice to have the option not to have to. Very satisfied with this purchase.

    Incredible!

    I already had an exhaust system on my car but the mid range acceleration was lacking on my car. With this intake installed, even not tuned (with the insert), it fixed that slow mid range problem and then some! My car goes straight up to high speeds without any slack, it's fantastic! It also only took 35 minutes to install and I was only charged $50 by my mechanic. I definitely recommend this to anyone who's looking for an intake.

    Of course it's quality, it's Roush

    I'm not really a performance guy, but my friends who are told me I needed to install a CAF, and because I already have some Roush parts on my 2006 5-speed convertible, picked the Roush CAF, which has good reviews. Thought I'd get a little extra HP and better engine sound, but more importantly, to me, it would look cool when I popped the hood ha-ha. After install, I did notice a small response improvement overall, but more in third and fourth gear when I floored it. As far as sound, kind of minimal difference as I have a Bassani exhaust, which already sounds great (and loud), so I think the better engine sound is more prominent in stock exhaust systems. While I'm not a performance guy, I am a guy who expects and appreciates quality, and I wasn't disappointed. Foolproof install instructions with great illustrations, and all the hardware in the kit said "quality". I also have a shaker hood, so I had to make a hole in the back of the filter box to bring in the hose that funnels scoop air to box, and there was some hose interference with the shaker engine cowling, so I had to remove cowling, cut out some plastic, but doesn't look too bad. All in all, a great mod.

    What are you waiting for??

    I love the sound that the intake produces. The throttle response has definitely changed for the good, love it. I like the option of not having to have my car tuned, but I can in the future. Got the CAI on Friday afternoon, and it took about an hour to get on. I even bought a Roush grille emblem. Can't wait to get it tuned.

    The roush air intake fits well, it dose not need a tune "if" you use there limantor pipe comes with the intake. It says just for the California emissions, but when I didnt put it in the car wouldn't run, so now I have to buy a tune for it to get the max prorfomace

    Love this CAI. Decent gains, nothing crazy, but subtle. It looks great and doesn't require a tune because of the internal sleeve (adapter) which I removed to accommodate my BAMA tune. After the tune...gains in terms of power and torque were significant. The Rousch brand is synonymous with Ford Racing so you really cannot go wrong with any Roysch products for your Mustang.
