Product Description

Roush Cold Air Intake Kit for 2005-2009 Mustang GTs.

Upgrade your 2005-2009 Ford Mustang GT with this Cold Air Intake Kit and unleash an additional 17 hp and 9 ft-lb of torque out of your engine, while increasing your fuel efficiency. The kit features the ROUSH air filter, air dam, and induction tube.

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 air intake unit. Air first comes into the Air Dam, which keeps out hot air from the engine compartment. The result is that the air entering the filter is cooler and dense, providing for a more potent air charge.

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.

Once air passed through the filter, it is taken to the engine through a Modular Intake Tube (MIT) that can improve airflow up to 400 CFM over the restrictive stock intake tube. Made from cross-linked, high-density polyethylene, the MIT straightens out air flow by providing a smooth, unrestricted path that increases air flow to the engine.

The kit includes all the necessary hardware, making it quick and easy to install. The "ROUSH" logo is also featured on the kit, thereby stamping your car with the mark of the leader in automotive performance. As a result, this kit not only makes your car faster, it makes it look faster when you open your hood.

Rated 5 out of 5 by from Awesome product! Got my Roush intake two weeks ago. Installtion was pretty straight forward. Felt the power increase right away! Can't wait to remove the tube insert and get a tune to unleash its full potential. Also looks awesome underneath the hood!!

Product Questions

Hi, I have this kit on my 2008 Roush Mustang GT and I'm looking for a replacement air filter head. Could you get that for me? Or any from the universal filters that would fit this kit.

Can the Roush 402099 cia filter also be converted to tune like the BBK version ?

Asked by: chloe
There is nothing to change on this to require a tune. Adding a tune will still be beneficial and will increase performance.
