Optimize Your Exhaust Setup the Right Way

Working on a custom or high-flow exhaust system? Our O₂ Sensor Spacer is engineered for off-road, racing, and diagnostic testing use only.
It assists with sensor positioning and diagnostic evaluation of readings such as P0420 and P0430 when tuning or testing modified exhaust configurations.

Crafted from high-grade stainless steel with precision M18 x 1.5 threads, this spacer repositions the O₂ sensor to help reduce exhaust turbulence and ensure accurate diagnostic data.

Installs in minutes — no cutting, welding, or special tools required.
⚠️ Not for use on public roads or emission-controlled vehicles. Always check local laws and regulations before purchase or installation.

  • Universal Fit: M18 x 1.5 thread fits most O2 sensors and aftermarket exhaust setups (works with Honda, Toyota, Ford, BMW, and more)

  • Eliminates CEL Codes: Helps reduce P0420/P0430 after cat deletes or performance exhaust mods

  • Built to Last: Corrosion-resistant stainless steel holds up under extreme heat and pressure

  • Fast Installation: Thread it in — no special tools or mods required

  • Performance-Ready: Ideal for setups with high-flow cats, failing catalytic converters, race headers, or test pipes
