The install was easy. Maybe 40 minutes total. I did get a custom tune the same day so it's hard to rate h.p. and or milage from the intake alone. BUT my truck definitely runs better and gets better milage. 10% gain in h.p. and torque to the wheels. Significant indeed. It sounds good and runs soo much better. It kicked my old bully dogs tail.
