Standard Ignition KS253 sensor for the 1997-1998 BMW Z3 6-cylinder 2.8L, the 1998-2000 Z3 6-cylinder 3.2L and other vehicles detects engine knock and sends a voltage signal back to the engine computer.
- Every unit is tested with an accelerometer-based vibration test for trouble-free operation
- Automated data acquisition system monitors sensor output for appropriate voltage at the specified frequency range
- Knock response up to 1000 Hz to follow shifts in engine knock frequency across a broad range of conditions
- Bolt-mount sensor with an oval plug-in connector and four female bullet terminals

Pinging under load, a lit check engine light or a drop in power can mean the sensor is worn, though the wiring connector or the spark plugs can be behind them too, so find the cause before replacing it. The fitment calls for one sensor per vehicle, and this listing is one sensor.
Fits
The fitment covers a wide range of BMW models, led by the 1998-1999 BMW 323is 6-cylinder 2.5L and the 1996-1999 BMW 328i 6-cylinder 2.8L. Own a BMW we haven't named? Find your year and engine in the "Vehicles it fits" section.
