"I installed this on my 2002 f150 5.4 I noticed a difference right away there is a whistle but I like it There isnt a huge amount of power like a supercharger but at low to mid range its great especially nice for all these hills and mountains around here"

"Installed in 1 hr with help of 15 yr olg grandson, more power thru low to mid range, runs thru gears smoother, less strain on motor. Very pleased after first two trips. Haven't had time to check MPG but so far so good."
