Straightflow Lambda Sensors bushing 45degree M18x1.5 D25 L20-30

Description

The Straightflow 45 Lambda Bushing is a 45 degree angled, precision-machined stainless steel weld-in bushing for lambda (O2) sensors, with an M18x1.5 internal thread, a 25mm outer diameter and a 20-30mm length (D25 L20-30). Straightflow lists it for angled sensor mounting where space is limited or more clearance is needed.

What Straightflow states

Straightflow says M18x1.5 is the standard thread for most lambda sensors, so the bushing suits OEM and aftermarket O2 sensors. The 45 degree angle lets the sensor sit away from nearby parts, chassis members or tight engine bay areas, 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 exhaust 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 the space around the pipe before ordering the Straightflow 45 Lambda Bushing.

This bushing is welded into the pipe, so plan the job with your installer. If you are asking us about the Straightflow 45 Lambda Bushing, quote the supplier code so we can match the exact item.
