That Check Engine Light After Exhaust Work, Solved
Position the O2 sensor for readings the ECU recognizes as normal — internal mini catalytic converter, magnetic induction spacing, M18x1.5 threads, without welding or permanent exhaust modifications.
Why Is This Adapter Perfect for You?
✔ Processes exhaust gases before they reach the sensor: The internal mini catalytic converter treats exhaust gases before sensor contact. It is designed to help address false codes and check engine lights after exhaust modifications, including high-flow catalytic converter or aftermarket exhaust installations.
✔ Durable stainless steel with secure M18x1.5 threads: The stainless steel body is built to withstand extreme exhaust temperatures. Internal and external M18x1.5 threads provide secure connections between the exhaust bung and O2 sensor on compatible vehicles.
✔ Installs without welding or permanent modifications: The compact bolt-on design uses basic hand tools and requires no cutting, welding, or permanent exhaust changes. The package includes two adapters for vehicles with multiple O2 sensors or a spare.
