SpeedFactory Billet B-Series Breather Port Plug
Upgrade your Honda or Acura B-Series engine with the SpeedFactory Billet B-Series Breather Port Plug, designed to replace the OEM "black box" breather port. This precision-machined plug fits B16, B18, and B20 engines and allows you to use the two M28 threaded holes on the rear of the engine block for your aftermarket oil catch can or breather system, ensuring proper crankcase ventilation for high-performance applications.
CNC machined from 6061-T6 billet aluminum and finished with a durable black anodized coating, this breather port plug offers long-lasting corrosion resistance and strength. Dual O-rings create a tight, leak-free seal, while the laser-etched SpeedFactory “SF” logo adds a professional, high-performance touch.

Installation Tip:
For best results, clean both the port in the block and the fitting thoroughly with brake cleaner. Coat the fitting with HondaBond or Permatex Ultra Grey, insert it into the block, and allow it to cure for 24 hours. This ensures a secure bond and prevents blowout during high crankcase pressure events (such as during a piston failure).
Ensure proper crankcase ventilation and protect your high-performance B-Series engine with the SpeedFactory Billet B-Series Breather Port Plug. Ideal for use with oil catch cans and aftermarket breather setups, this plug combines precision engineering, durability, and professional style.
