G2 Lambda Sensor - 1.3-1.8

This unheated 1-pin lambda sensor is designed for early closed-loop fuel injection systems, monitoring exhaust oxygen content to help the ECU maintain the correct air-fuel mixture. Mounted before the catalytic converter, it plays a key role in fuel economy, emissions control, and smooth engine running.

A tired or failed lambda sensor can cause poor fuel consumption, rough running, hesitation, or failed emissions tests. This direct-fit replacement restores accurate exhaust gas feedback and reliable operation on classic Volkswagen petrol models from the late 1980s and early 1990s.

Ideal for routine servicing, fault diagnosis, or emissions repairs on older Bosch-equipped systems.
