Description
CSR Billet Crankcase Breathers for 1999-2017 Twin Cams:
- Made out of billet aluminum
- Uses the updated style umbrella valves to accurately and instantly release crankcase pressure while preventing outside atmosphere to be pulled back into the engine
- Lighter and stronger than the stock steel crankcase breathers
Cycle Solutions Inc uses these crankcase breathers in our high horsepower motor builds because they are heavy duty and are far superior over stock steel crankcase breathers.
