gpd 1815036 Ignition Knock Detonation Sensor

The gpd 1815036 is a direct-fit ignition knock sensor (also commonly called a detonation sensor) designed to restore proper engine management function. Mounted on the engine block, cylinder head, or intake manifold, the knock sensor monitors for the unusual vibrations caused by engine pre-ignition or detonation and signals the engine control unit to adjust ignition timing accordingly — protecting the engine from damaging knock events.

Key Features:

• Direct-fit replacement knock sensor
• 2-terminal female connector with blade-type terminals
• Rectangular connector shape for secure, precise mating

Engineered to meet OE performance standards, this gpd knock sensor offers a reliable, straightforward replacement for worn or failed units. Fits select 1985–2008 BMW models.
