Review on Enhance Performance with K&N Cold Air Intake Kit: Boost Horsepower | Compatible with 2015-2017 SUBARU (WRX STI, Impreza WRX STi, WRX) 69-8007TWR by Ron Turner

Works as advertised! Easy installation, nice look, engine sound is great, not too loud but nice. One minor complaint, they didn't send enough rubber for the heat shield, and the instructions don't mention using part of the rubber gasket after trimming the edge of the heat shield to use the rest of the cut for stuffing. Hole in the heat shield through which the inlet pipe must be routed. never mind I called K&N customer service and they sent me an extended piece of rubber grommet to fix the problem, otherwise I'm spot on. Good shipping to me! Thanks!
