TP Engineering is proud to introduce the Open Scramjet Air Cleaner for your Harley-Davidson touring bike. Now you can have the same air cleaner used on our award winning TP pro series 121 motor on your 2008 and up fuel injected FLH. Featuring a polished 6061-T6 billet face plate with clean styling, its open design highlights the air filter. Our innovative backing plate incorporates channels that will funnel any oil that may mist through the breather bolts back into the motor, reducing oil contamination of the air filter. Plus, its performance will gain you an extra 5 horsepower at the rear wheel!
