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.

Stylish, comfortable long‑sleeve polo
Size: X-Large, Color: Royal Blue, Size: X-Large, Color: Royal Blue
I recently tried out this Lexiart long‑sleeve polo and was pleasantly surprised by how well it balances style and everyday wear. The textured knit gives it enough visual interest (so it doesn’t feel like just another plain jersey shirt), and the slim‑fit design helped create a clean silhouette without being overly tight. The collar and button‑placket feel more polished than a typical tee, which makes it easy to dress up a bit for smart‑casual settings. The fabric is comfortable and breathable enough to wear indoors or layered under a jacket. The length and fit were generally good — the sleeves hit just right and the body length worked for casual wear.

Nice heavy duty long sleeve shirt
good looking and good fitting long sleeve shirt. I didn't notice the flag on the sleeve until I unpacked it. Nice touch. Color is true. Material is indeed stretchy. I cannot determine the fabric blend but it is comfortable. The care instructions are included on a card, not on a tag, not be sure to pay attention to it. I am 5'10' and 235, the 2X fits me well.
