GPD 1811887 Ignition Knock Detonation Sensor Direct Fit Replacement

The GPD 1811887 is a direct-fit replacement ignition knock sensor (also known as a detonation sensor) engineered to meet or exceed OEM fit, form, and function for a wide range of BMW models. This sensor plays a critical role in protecting your engine by continuously monitoring for abnormal vibrations caused by engine pre-ignition or detonation (knock), allowing the engine control module (ECM) to adjust ignition timing accordingly for safe, efficient operation.

Key Features:

• Direct Fit Replacement – Designed as a plug-and-play OEM replacement with no modifications required
• Meets or Exceeds OEM Specifications – Engineered to match the original sensor's fit, form, and function
• 100% Tested – Each unit is tested for durability and performance before leaving the factory
• Professional Quality – Suitable for both DIY installation and professional shop use
• Sold Individually – Single knock sensor included

The knock sensor is typically mounted on the engine block, cylinder head, or intake manifold. When the sensor detects abnormal vibration signatures associated with pre-ignition or detonation, it sends a signal to the ECM to retard ignition timing, preventing engine damage and restoring efficient combustion. A failed knock sensor can trigger a check engine light, reduce fuel efficiency, and leave the engine unprotected from harmful knock events.
