Straightflow Lambda Sensor Adapter 90degree Euro4

Description

The Straightflow Euro4 90 Adapter is a 90 degree stainless steel lambda sensor adapter, also called a spacer, for repositioning the oxygen (O2) sensor in Euro4 exhaust systems. Straightflow lists it for modified and performance exhausts, where the 90 degree angle moves the sensor and reduces direct exhaust gas exposure at the sensor tip.

What Straightflow states

Straightflow says that after fitting sport or high-flow catalytic converters, decat pipes or a custom exhaust, the engine management on a Euro4 vehicle may detect altered catalyst readings and trigger a check engine light. It says the spacer slightly limits direct exhaust flow to the sensor tip, which can help reduce unwanted fault codes on modified exhausts.

Straightflow says the 90 degree design suits layouts where space behind the catalytic converter is limited, straight spacers cannot be fitted, maximum sensor repositioning is needed or the exhaust routing needs side clearance. The stainless steel construction resists high exhaust temperatures, corrosion and vibration.

Fitment

This adapter is listed for Euro4 vehicles but has no specific car list. Check your emissions standard and the space around the sensor port before ordering the Straightflow Euro4 90 Adapter.

The adapter fits between the sensor port and the O2 sensor, so plan the job with your installer. If you are asking us about the Straightflow Euro4 90 Adapter, quote the supplier code so we can match the exact item.
