SpeedFactory Billet B-Series Breather Port Plug

The SpeedFactory Billet B-Series Breather Port Plug was designed specifically for use on Honda/Acura B-Series engines to block off the OEM "black box" breather port.

This allows you to utilize the (2) M28 threaded holes on the back of the engine block for your aftermarket oil catch can/breather system, resulting in the proper crankcase ventilation your high performance engine needs.

  • Precision CNC machined from 6061-T6 billet aluminum
  • Black Anodized finish adds durability and eliminates corrosion
  • Dual O-rings for a tight, leak free seal
  • Laser-etched SpeedFactory “SF” logo

Installation Notes: We recommend thoroughly cleaning the port in the block and the plug with brake parts cleaner prior to installation, and then liberally coating it with HondaBond or Permatex Ultra Grey and allowing it to cure for 24hrs before use. This will act both as lubricant to facilitate installation and then will setup and bond the plug into the block so that it does not blow out in the case of abnormally high crankcase pressures such as during the event of a piston failure.
