[Good Quality]: This oxygen sensor adapter is made of high-quality stainless steel, which is strong and durable, not easy to rust, ensures good sealing, is waterproof, high-temperature resistant, and is very strong and durable, so the seal can be used for a long time. The thread is ground with special tools, with high precision and good repeatability.

[Easy Installation]: The use is simple and user-friendly. Simply align the interface of the spiral pattern with the interface where the spare parts are to be installed.

[Special Design]: Built-in mini catalytic converter filtering network, effective in removing CEL and fault code P0420. Thread with special tools, perfect precision and repeatability.

[Practical Function]: This lambda sensor eliminator extender is necessary if you use the HHO system or test pipe. It can also be used in car pipes for better fuel economy. Increase the distance between the lambda sensor and the exhaust system.

[Wide Application]: This oxygen sensor is a universal 18mm threaded socket that fits most vehicles with M18 x 1.5 holes for oxygen sensors. It applies to most modern vehicles and easily screws into upstream and downstream O2 sensors and car exhaust pipes, and fits the threaded sockets or tools for most O2 sensors in cars.
