What Straightflow states

Straightflow says M18x1.5 is the industry standard thread for most OEM and aftermarket lambda sensors. The stepped outer diameter gives flexible installation options and a strong welding base on different exhaust pipe sizes, and the stainless steel resists corrosion, oxidation and extreme exhaust temperatures.

Straightflow lists it for O2 sensor installation, custom exhaust fabrication, turbo and performance builds, motorsport and stainless piping. It is welded into the exhaust pipe, with professional TIG welding recommended, and Straightflow states it is a universal fabrication part, not a direct OEM replacement.

Fitment

This is a universal fabrication part, so there is no car list. Check your sensor thread and pipe size before ordering the Straightflow Lambda Bushing.

This bushing is welded into the pipe, so plan the job with your installer. If you are asking us about the Straightflow Lambda Bushing, quote the supplier code so we can match the exact item.
