ISR O2 Sensor Adapter for Nissan SR20DET

Our O2 sensor adapter for the SR20DET. A small but useful piece if you're running an aftermarket turbine outlet and don't want to swap to a different O2 sensor just because the bung doesn't match.

What It Does

Adapts the larger "fat-type" O2 sensor hole found on common aftermarket turbine outlets so you can run the skinny-type O2 sensor from your stock setup. Saves you the cost of a replacement sensor and the hassle of tracking down the right one. Can also be used as a block-off plug if you don't need an O2 sensor in that location.

Fitment

Works with Megan Racing, GReddy, and ISR aftermarket turbine outlets on the Nissan SR20DET. Compatible with skinny-type O2 sensors.
