Review on Spectre Performance Air Intake Kit SPE-9033 for 2015-2019 Ford F150: Maximize Horsepower and Torque Gain by Eric Ramen

Grows well. looks clean There is no fuel consumption (almost 1000 km driven). There's also no notification of extra power. I've had an issue with whistling between 2-3,000 rpm and a chugging noise (as if air is trying to escape) at idle, but the gaskets may just need to be re-tightened. Even the not really annoying sounds look good and growl well. It is very easy to install. Updated 01.11.18. The growl is still nice, but I still can't get rid of the popping and whistling. Other than that, this is my second Specter. The last was on the 2011 Silverado 5.3L. I had no problems with it and liked the sound so I went with the F150. I probably won't keep it for long. The pops and whistles at idle are more noticeable now that I've had it longer.
