O2 Sensor Adapter with Internal Element and SS304 Stainless Steel Body for M18x1.5 Threads

Reduce Unwanted Engine Warning Lights with This Sensor Adapter

After exhaust system changes, a check engine light may appear at startup. It can be unclear whether there is a real issue or a sensor reading mismatch. This adapter is designed for use in modified exhaust setups where catalytic components have been removed for off-road applications.

This adapter installs between the existing sensor and the exhaust system using standard M18 by 1.5 threading. An internal element sits between the sensor probe and exhaust flow, moderating what reaches the sensor to reduce the chance of catalyst efficiency codes such as P0420 and P0430 appearing on the dashboard.

The body is made from SS304 stainless steel for resistance to heat and corrosion. The internal mesh is designed to withstand high exhaust temperatures. It weighs 0.088 pounds and installs directly into place without cutting or welding.

The threaded design allows installation or removal using basic hand tools. It is intended for off-road or closed-course applications where exhaust system modifications are permitted.

• INTERNAL FILTER ELEMENT: Internal structure moderates exhaust flow reaching the sensor to reduce catalyst code triggers in modified systems.
• SS304 STAINLESS STEEL BODY: Heat and corrosion resistant metal housing designed for high-temperature exhaust environments.
• M18 BY 1.5 THREADING: Standard metric thread size for compatibility with many exhaust sensor ports.
• P0420 AND P0430 CODE RESPONSE: Designed for setups where catalyst efficiency alerts appear after exhaust modifications.
• LOW WEIGHT PROFILE: Small inline design that adds minimal mass to the exhaust system.
• OFF-ROAD USE: Intended for non-road or controlled environments where exhaust modifications are permitted.
