✅ Why Choose This Over OEM or Knockoffs?

• No More Shearing Under Torque
  OEM and cheap aluminum copies have been known to fracture when torqued to spec. Our Onyx plug is tough, not brittle, with a ductile response that resists cracking under stress.

• Corrosion-Proof & Heat-Resistant
  Unlike aluminum, Onyx won’t seize, oxidize, or fatigue over time. It’s built to handle engine heat and vibration without compromise.

• Precision Fit, Clean Finish
  Designed to match OEM specs with a sleek matte-black finish — no sanding or polishing required.

• Hard to Find? Not Anymore.
  OEM parts are often backordered or discontinued. We manufacture on demand and ship globally, so you’re never stuck waiting.

• Trusted by Riders, Built by Engineers
  This isn’t a knockoff — it’s a performance upgrade. Designed by engineers who understand the failure modes of the original part and built to solve them.

⚠️ Note: O-ring not included. Compatible with OEM or equivalent O-ring.
