MIL Light Cheater – Lambda Sensor Spacer (M18 x 1.5) Fitting a de-cat or high-flow sports catalyst? Then you’re likely familiar with the common issue: an unexpected MIL (Malfunction Indicator Light) or EML (Engine Management Light) triggered by the post-cat lambda (O2) sensor detecting abnormal exhaust flow. This lambda sensor spacer helps to reduce or eliminate those warning lights by pulling the sensor slightly out of the direct gas stream, allowing your ECU to maintain proper readings without detecting a fault. 🚫💡 ⚙️ Key Features: ✅ Fitment: M18 x 1.5 – universal for most O2 sensor threads 🔄 Variety: Straight or right-angle style depending on current stock (both work identically) 💨 Helps reduce MIL/EML lights after fitting decats or performance sports cats 🧠 Recommended with a remap for full reliability and performance ⚙️ Simple DIY install 🚗 Why Use a MIL Cheater? When you install a decat or sports cat, the second lambda sensor may detect increased emissions due to the reduced filtration. This sensor extension tricks the ECU into reading emissions within an acceptable range – often preventing warning lights. ⚠️ Good to Know: This is not a guaranteed fix for all applications. It's a helpful aid, but for optimal results, a custom ECU remap is strongly advised. Suitable for both turbo and NA vehicles that use an M18 x 1.5 lambda thread. Designed for off-road or motorsport use only – check local laws for road legality. 💡 Avoid warning lights and enjoy your performance upgrades without compromise.🛠️ Install in minutes and keep your dash clean.
