The aFe kit was super easy to install. Removing factory air box/filter was the most difficult of the entire process. The cold air really opens it up, it breathes a lot better, and really let's the turbo work more efficiently. 06 6.0 F-250 with Banks exhaust, SCT tuner, EGR kit, and aFe cold air....fantastic set up! Fuel economy definately benefits.
