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.

Do one oil change myself and it’s more than paid for.
Color: Silver, Color: Silver
It is 74 mm. It’s nicely made of cast aluminum. It has a rough cast finish so it shouldn’t be difficult to hold on to. It does fit my Lexus filter and the price is very reasonable. It also fits the oil filter on my 1999 (antique) Harley Davidson Heritage Classic. Which is the primary reason I ordered it. I don’t know this for certain but I suspect it will fit all HD EVO engines. That would be 1984 through 1998 except the Heritage which didn’t change to the 88 Twin Cam until 2000.
