The MEAT & DORIA 87414 Detonation Sensor is engineered to monitor and detect engine knock, also known as detonation or pinging. This critical component plays a vital role in maintaining optimal engine performance and preventing potential internal damage.

The ECU then adjusts ignition timing in real-time to suppress the knock, ensuring the engine operates within its designed parameters. This proactive measure helps to preserve engine health and longevity. Reliable and built to OE specifications, the MEAT & DORIA 87414 is designed for a direct fit and straightforward installation. It is an essential part for maintaining the efficiency and responsiveness of your vehicle's engine.
