Review on K&N 63-1122P Harley Davidson Performance Intake Kit: Unleash Your Bike's True Potential! by Jessie Drury

I bought this for my 2012 Street Glide. I could definitely tell the difference with this intake; You also need a level 1 boot. I also installed new overhead silencers. The only problem I wasn't aware of, and now you know, is that after you took the old air filter off and installed the new K&N, a big, ugly throttle body was exposed. I had to purchase a Kuryakyn 8659 Throttle Servo Motor Cover to protect the wires and module which is about $70 and isn't the prettiest bit of chrome. I wish I could just have the Harley dealer fit the Stage 1 Air Kit. I love K&N, but this was a pain in the ass.
