M8 Additional Head Ventilation System for Harley Softail Street Bob Fat Boy Breakout

Ensure clean engine air. Ride stronger and longer.

The stock design allows oily gases to enter the throttle body and burn there, causing carbon deposits and power loss. The NICECNC breather kit captures oily gases from the engine and vents them outside through the air filter, so only clean air enters the combustion chamber. Cleaner air means better combustion, longer engine life, and less oily contamination.

Features:

• Cleaner combustion = longer engine life.
  
• The transparent front cover allows you to monitor the internal gas pressure at any time and manually release it if excessive oily gases accumulate.
• Precisely CNC machined, black anodized.
  Made from high-quality aluminum with a subtle black anodized coating, matching the factory design of your Harley. Looks like it belongs there.

Item specifications:

• Brand: NICECNC
• Condition: New

⚠️ Important note:

This breather kit was specially developed and tested for use with the original Harley-Davidson air filter (OEM). Compatibility with aftermarket air filters cannot be guaranteed; their use may result in improper fit or reduced performance. We strongly recommend using this kit in combination with the factory air filter for optimal results.
