AIRTEC Motorsport MIL Light Cheater

AIRTEC Motorsport MIL light cheater.

If you fit a de-cat or high flow sports catalyst to your car, you could run the risk of having an engine light turn on. This is usually due to the fact that the sensor is reading the added exhaust gas flow and it could identify this as a fault. This lambda sensor extension may solve this problem easily, however we do recommend a re-map to ensure the issue is resolved.

Note: NEVER fit this to the primary Lambda sensor before the catalyst, doing so can cause engine damage.
It must ONLY be fitted to the O2 sensor, which is the sensor found AFTER the catalyst.
