Features & Benefits

  • Precise M18x1.5 Thread — Matches the industry-standard thread pitch used on the vast majority of O2 bungs, oxygen sensor bungs, and lambda sensor ports found on exhaust manifolds, downpipes, and turbo exhaust hardware.
  • 19 mm Hex Head — Fits a standard 19 mm wrench for straightforward installation and removal — no specialty tools required.
  • Versatile Application — Whether you're plugging a downpipe bung after relocating an oxygen sensor, capping off an unused manifold bung during a build, or tidying up a standalone exhaust plug on any gas or diesel setup, this plug gets the job done.
  • Clean, Secure Seal — Threads in flush and tight, eliminating exhaust leaks from open sensor ports and keeping your exhaust system performing as intended.
  • Simple, Affordable Hardware — A low-cost solution that solves a real problem without overcomplicating the parts list — exactly the kind of detail-oriented exhaust hardware that separates a clean build from a sloppy one.
  • Sold by BSI Inc. — Backed by the same team behind Black Sheep Industries, supplying quality turbo and exhaust hardware to builders across North America.
