Universal O2 Sensor Adapter M18×1.5 – Universal Diagnostic Extension

Reliable Adapter for Exhaust and Sensor Testing

This O2 sensor adapter is designed to support off-road and diagnostic applications where exhaust modifications may affect oxygen sensor readings. It helps simulate standard backpressure conditions, providing more stable O2 sensor readings during vehicle testing and performance evaluation.

Precision Engineering and Durable Build

Constructed from high-quality stainless steel (SS304), this adapter ensures durability and long service life. The integrated mini catalytic core is engineered to help maintain sensor efficiency in non-road environments without the need for additional extensions or fittings.

For Off-Road and Diagnostic Applications

Ideal for performance enthusiasts and workshop professionals, this adapter is intended for off-road or track testing only. It should not be installed on vehicles operated on public highways, as it is not a replacement for an OEM catalytic converter.

Easy Setup for a Smooth Experience

Featuring standard M18×1.5 threading, this adapter installs quickly into most O2 sensor ports. Simply screw it into place for a secure fit during testing procedures no specialized tools or wiring required.

Frequently Asked Questions

Q: Can I use this adapter on public roads?
A: No. This adapter is for off-road, track, or diagnostic use only. It is not approved for vehicles operated on public highways.

Q: Does it work with my O2 sensor?
A: Yes, it’s compatible with standard M18×1.5 threaded O2 sensor fittings used in most exhaust systems.

Q: What does the mini catalytic core do?
A: It helps maintain more stable O2 sensor readings during diagnostic or off-road testing by moderating exhaust flow through the sensor area.
