Unleash the hidden power in your 2011-2014 3.7L V6 Mustang with this premium quality ROUSH Performance Cold Air Intake Kit!

Cold air induction is a more efficient air intake method than the factory air filtering process. Consequently, unrealized power and fuel efficiency that would normally be restrained by the stock air intake unit is attained. ROUSH Performance cold air intakes feature three main improvements: upgraded air dam, high flow air filter media, and cold air induction tube.

The first step in the air induction process is the air dam. Upgraded air dams keep insulate 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 second step is the air filter media. ROUSH Performance carefully selects the media to provide upgraded air flow while still keeping out as much dirt from the engine as possible. Once the air has passed through the filter, it goes through the induction tube. Each of ROUSH's Mustang cold air intake kits feature induction tubes designed to provide upgraded air flow while continuing to insulate out hot air from the engine bay.

Included with this kit will be a new induction tube, complete airbox assembly, premium synthetic washable/reusable filter (pre-oiled), and all necessary hardware and instructions to install.

This kit is also backed by the ROUSH 90 Day Limited Parts Only Warranty.

We recently purchased a 2014 v-6 mustang for my wife. She loves it. I had a little extra money, so I went to the Roush website and purchased a cold air kit and the muffler kit. My daughter and I put on the cold air kit and couldn't believe the difference in sound and performance. The next day I took it to the Ford place but they refused to put the mufflers on, so I went to a local shop and he did it for $38. When I left there I almost lost it. It was howling and screaming like a race car. I had to ride around for a while before I could take it home. My wife went to the store and when she returned she had the biggest grin on her face I have ever seen. Thanks a lot Roush, my wife has been so nice to me since then that it was worth 3 times the price. Sincerely, Tim L PS let me know of anymore upgrades. I'm interested!
