Lambda Sensor Adapter 90° Euro4

Lambda Sensor Adapter 90° Euro4 is designed to reposition the oxygen (O2) sensor in modified exhaust systems of Euro4 vehicles. The 90-degree angled construction allows the lambda sensor to be relocated away from direct exhaust gas flow, which can help reduce catalyst efficiency related fault codes after exhaust upgrades.

This adapter is widely used in performance and custom exhaust applications.

Designed for Euro4 Emission Systems

Euro4 vehicles use oxygen sensors to monitor catalytic converter performance and emissions efficiency. After installing:

• Sport catalytic converters

• High flow catalytic converters

• Decat pipes

• Custom exhaust systems

engine control units may detect altered readings and trigger a check engine light.

The 90° lambda spacer helps by repositioning the sensor to limit direct exhaust gas exposure, potentially reducing unnecessary warning lights in modified setups.

90° Angled Design for Tight Installations

The 90-degree design is ideal when:

• Space behind the catalytic converter is limited

• Straight spacers cannot be installed

• Maximum sensor repositioning is required

• Exhaust routing requires side clearance

This configuration provides improved fitment in compact exhaust layouts and engine bays.

High Quality Stainless Steel Construction

Manufactured from durable stainless steel, the adapter offers:

• High temperature resistance

• Corrosion resistance

• Long-term durability

• Secure and stable installation

It is engineered to withstand extreme exhaust temperatures and vibrations in both daily driving and performance applications.

Key Features:

• 90° angled lambda sensor adapter

• Designed for Euro4 vehicles

• Stainless steel construction

• High temperature resistant

• Helps reposition oxygen sensor

• Suitable for modified exhaust systems

Lambda Sensor Adapter 90° Euro4 is a practical solution for exhaust modifications requiring improved oxygen sensor positioning and better installation flexibility.
