The all-new 2015 Mustang 5.0L ROUSH V8 Cold Air Kit is more efficient air-intake than the standard stock air box. Cold air induction allows for latent potential in power and fuel efficiency that would otherwise be restricted, as well as providing reduced pressure drop. A custom tune is not required as this CAI system was engineered and tested specifically for this application ensuring MAF signal performance matches factory settings. As a straight bolt on, with no tune, it’s possible to see gains of 10hp and 8 lb-ft of torque, a noticeable increase. With this kit you can also remove the MAF insert for a 105mm bore MAF and Custom tune your PCM for even more power.

Our dry filter is proven to retain its shape under high airflow and is composed of an inner and outer layer of wire mesh for durability and reliable support of filtration media. The filter requires no oiling and is easily washable for re-use.

Included in the kit is the air filter with clamp, injection-molded lower air box/tray with installed EPDM foam hood seal, Blow Molded clean air tubes, heat extractor foam insert, and all required mounting hardware. The kit utilizes all factory emissions and vacuum lines. Factory mounting locations and hardware are utilized to allow for quick and easy installation.
