Review on Enhance Your Ford F150: K&N Cold Air Intake Kit 🔥 for Increased Performance and Horsepower - 2015-2019 Ford F150, 5.0L V8, 77-2591KP by Charles Quinones

I was hoping this would be a good addition to my 2017 F150 SCREW. It turns out that it whistles like crazy around 1700-1800 rpm (cruising rpm) and increases the under-hood noise in the mid-range of the rev curve. Pretty loud to be honest. After reading some reviews on other sites I found out that the whistle is indeed present on the stock pickup, it's just that the Ford dampens it well. I can confirm that even with burst shooting at roughly the same RPMs, there's a slight whine. If I were 22 again I'd certainly love the growl on this recording, but for a truck my wife uses fairly regularly, it's just too annoying to put up with. Send it back to Revain and use $$$ on the Flowmaster Force II exhaust system!
