AIRTEC Motorsport MIL Light Cheater – Lambda Sensor Extension for De‑Cat and Sports Cat Setups
Stop the nuisance of a check engine light after a de‑cat or high flow sports catalyst with the AIRTEC Motorsport MIL Light Cheater. This lambda sensor extension spaces the post‑cat oxygen sensor away from direct exhaust flow, which may help reduce false catalyst efficiency faults and prevent the MIL/CEL light from illuminating. For the best long‑term results, we still recommend an ECU re‑map.

- Helps prevent check engine light after de‑cat or sports cat installations
- Lambda sensor extension designed to reduce post‑cat O2 sensitivity
