Product Description

2005-09 Mustang GT Roush Cold Air Intake Kit
This Roush cold air intake kit for your 2005-2009 Mustang GT 4.6L not only adds power & performance, it also increase fuel economy. Add up to 17 horsepower and 9 ft/lbs of torque simply by bolting on this intake kit. Features a high quality washable filter for more airflow. Does not require a tune. Comes with insert that can be removed if a tune is desired.

Cold Air Induction
Cold air induction is a more efficient air intake method than the standard air filtering process. As a result, cold air induction can unleash the latent potential in power and fuel efficiency that is normally restrained by your stock Mustang air intake unit.

High Quality Washable Filter Element
The ROUSH air filter media is a synthetic nano-fiber material that traps the smallest dirt particles that ordinary cotton-gauze "performance" filters can’t capture. Based on SAE standards, ROUSH air filters capture almost twice the percentage of 2 micron particulates, and more than six times the amount of 0.5 micron particulates than our competitors’ filters. Furthermore, ROUSH air filters are constructed using the finest materials available today, featuring a hand-poured urethane body that won’t crack, curl or shrink like other rubber or plastisol units used by our competitors. ROUSH air filtration performance is second to none. This ROUSH air filter is 100% washable, reusable and features a lifetime warranty. The ROUSH Cool Air Dam surrounds the filter, helping to keep out hot air from the engine, further maximizing performance.

- This product does NOT fit ROUSHcharged vehicles.
- This unit is currently not street legal in California, Connecticut, Maine, Massachusetts, Pennsylvania, Rhode Island, New York, and Vermont.

Simple to install. I bought this for my girlfriend's 2009 Mustang GT after having a Magnaflow exhaust installed. It really opened it up, and the mileage went up too! The guys at LRS were very polite and knowledgeable. I am an engineer in Tyler, but when it comes to her Mustang I will definitely make the trip for more goodies!

Yes, I would recommend this item to a friend!

4 Stars   Roush CAI Installed
By on 4/6/2015
Image uploaded by Chris P Purchased the Roush CAI for my 2006 GT a few weeks ago. I received it in the time allotted and it was packaged well. I installed the filter last weekend and the instructions were pretty good. I will say I wish Roush would ship the filter with slightly longer hose clamps as two of the ones that are shipped were a little hard to get to fit. Overall, install was fairly easy and the filter looks great under the hood. I would definitley purchase this product again and would recommend to others.

Bought this a week ago , easy install with provided detailed instructions. Didn't notice much of a difference but pretty good for just being a CAI without a tune. Only thing would be that Roush should include bigger clamps! Great product

The product looks awesome and was easy to install. I haven't seen much improvement in performance since I haven't installed a tune to be able to remove the restrictor cone from inside the tube. I hope to test this very soon!

Installed it on my 2006
GT.First things first....Very happy with LMR!! Ordered sunday night,processed and shipped on monday.and delivered on thursday.Pretty good from Texas to Pennsylvania.As for the product,i was a bit disappointed that they have not taken care of the hose clamp issues most buyers run into.The two for the throttle body i used on the air dam coupler,and the one off the stock tube i used on the throttle body.Need one more bigger one for the coupler.Typical installation.Loose fitted everything,and tightened it all down.It looks good with the ROUSH name on the tube.Having Roush extreme axle backs installed on tuesday,and hope to soon have it tuned...

Yes, I would recommend this item to a friend!

I bought this to replace a cheap cold air setup that was on my 2007 GT when I bought it. It took 30 min to install and it fits perfect. Looks much better than the old unit.

Yes, I would recommend this item to a friend!
