An external Breather Kit is preferred with any Air Cleaner System.  This allows for only clean cool air to go into the air cleaner and engine, increasing performance and engine longevity. 


The EPA has required Harley to route hot, dirty, oily crankcase air back into the air cleaner compromising the performance of your engine. This vents it without compromising the performance and longevity of your motor.

With this breather system you will experience a slight performance increase.  This is because engines like Cold Dry air!

Fits All Twin Cam Models - 2000-Up Touring & Softail, 1999-Up Dyna

When ordering, choose between cable operated throttle and throttle by wire.

When ordering, you have a choice between a Filter, or a Black or Chrome Catch Can.

  * Please Note: Using Black Hose Finishers on the black BRAIDED hose is a Very TIght fit.  Soaking the end of the hose in hot water will soften the rubber up, making it a little easier to slide on to the fitting.

PLEASE NOTE:  Even though it is in the title, at the top of the description at the top of this page, and in the Fitment notes above.  This is for Twin Cam's, it does NOT FIT Milwaukee-Eight engines.
