Lambda / O2 sensor spacer with nut, 90°

On cars meeting Euro 3 and later standards, the second lambda sensor sits after the catalytic converter and monitors its efficiency. If it detects a deviation, the ECU shows a fault (usually CHECK ENGINE) and, depending on the make, the engine may enter limp mode with a loss of power. This fault can appear, for example, with a sports (high-flow) catalyst.

The spacer moves the sensor out of the main exhaust flow, which helps against this fault. It can also help with LPG systems where a very rich mixture triggers CHECK ENGINE.

Important: removing the catalytic converter on cars driven on public roads is not permitted. The spacer is intended for sports (high-flow) catalysts and for race cars.

Specifications

• Thread: M18x1.5
• Angle: 90°
• Included: nut

Installation

Unscrew the lambda sensor, screw the spacer into its place, then screw the sensor into the spacer.
