O2 Sensor Spacer, Stainless Steel O2 Sensor Adapter with M18x1.5 Thread, Oxygen Sensor Spacer and Extension for Exhaust
Stainless Steel O2 Sensor Spacer and O2 Sensor Adapter with M18×1.5 Thread for Exhaust
- The sensor sits exactly where it should: the oxygen sensor spacer holds the sensor in a precise position
- Exhaust heat and corrosion do not wear it out: SS304 stainless steel is heat resistant, durable and corrosion-free
- Threads right into the sensor port: precisely machined M18×1.5 threads match the standard O2 sensor mounting
- Fitting is quick: easy plug-and-play installation with precision machining
- No guessing at the install: an installation manual comes in the box
When you need your oxygen sensor held in a precise position, this spacer does that job and keeps the readings from the exhaust stable. It is made of SS304 stainless steel, so heat, wear and corrosion are not a worry, and the precisely machined M18×1.5 threads match the standard O2 sensor mounting.

As an O2 sensor extender, the adapter sits between the sensor and its port, and as an O2 sensor extension it keeps the same M18×1.5 thread. It installs with plug-and-play ease, and an installation manual is in the box. Let the exhaust cool before fitting it. Check your local emissions rules before installing; it is intended for off-road and track use.
