Ensure Clean Engine Air. Ride More Powerfully and for Longer.
The stock design allows oily gasses to enter the throttle body and burn, leading to carbon buildup and power loss. The NICECNC Breather Kit captures oily gasses from the engine, venting them out through the air filter, ensuring only clean air enters the combustion chamber. Cleaner air means better combustion, longer engine life, and less oily mess.
Features:
- Cleaner combustion = longer engine lifespan.
- Transparent front cover allows you to monitor internal gas pressure and manually drain when excessive oily gases accumulate.
- Precision CNC machined, black anodized.
Made from premium aluminum with a subtle black anodized coating to match the factory design of your Harley. Looks like it belongs there.
