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

In general I am happy with the purchase. Installation was easy except for one detail. When tightening the air filter with a clamp, the surface is too smooth for the filter to stick on impact. Some comments said they used a bolt to hold it in place, but I found a metal bristle brush with a drill to roughen the surface worked well and didn't budge. The manufacturer should add grooves or a concave surface in the opposite direction to keep it from slipping off.
