Roush Performance Products 421826 Cold Air Intake Kit, 1 Pack
The all-new 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 lo-fi 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
