Introduction

An oxygen sensor extender repositions the sensor farther from the exhaust manifold or catalytic converter. This adjustment helps avoid heat damage and improves sensor accuracy in modified exhaust setups.

  • Threaded design fits standard M18 x 1.5 oxygen sensor ports
  • Stainless steel construction resists corrosion from exhaust gases
  • Available in multiple lengths to match specific vehicle configurations

Choose the correct length to maintain proper sensor function.

FAQs

Most extenders feature M18 x 1.5 threads that match common oxygen sensor and exhaust bung dimensions.

If the sensor is moved too far from the exhaust stream, the ECU may trigger a code due to altered readings.

Compatibility depends on thread size and sensor type; verify specifications before installation.

An extender lengthens the sensor's reach, while a spacer adds distance without extending the sensor itself.

No welding is needed if an existing bung is present; the extender screws directly into the threaded port.
