Description

The Vibrant Oxygen Sensor Defouler is a J-style fitting designed for improved clearance when installing an O2 sensor. It features M18 x 1.5 threading and is constructed from stainless steel. Vibrant revised this defouler in mid-2021, making it shorter while retaining the 90-degree angle and threading.

This defouler accepts all standard O2 sensors with an 18mm thread measurement from tip to tip. It is intended to help resolve check engine lights related to catalytic converter efficiency without compromising engine performance.
