BMW M20 Crank Sensor Bracket Kit (EFI Conversion)

Take the hassle out of EFI conversions with our fully adjustable Crank Sensor Bracket Kit, designed specifically for the BMW E21 M20 engine originally equipped with K-Jetronic mechanical fuel injection.

Since these classic engines were never designed with EFI in mind, installing a crank sensor is often a major challenge. Our bracket solves that problem with a purpose-built, bolt-on solution.

Key Features:

• Fully Adjustable Design: Allows for fine-tuning both along the axis of the engine (front to back) and radially (in and out toward the trigger wheel) to ensure perfect sensor alignment.

• Built for EFI Conversions: Designed to make retrofitting modern engine management systems into vintage platforms easy and reliable. Tested with MaxxECU.

• Durable Construction: Laser cut from 4mm stainless steel for strength, longevity, and resistance to heat and corrosion.

• Designed for Bosch Sensor: Optimised for use with a Bosch crank sensor – included in the kit.

• Trigger Wheel Compatibility: Made to suit the solid vibration damper from later M20 engines, BMW Part #11231726351 – a direct-fit upgrade that works with the stock auxiliary belt and requires only a minor alternator adjustment.

• M20 Versatility: While designed with the E21 in mind, this bracket may also fits M20 engines in the E28, E30, and E34 platforms.

  ⚠️ Important Fitment Notice:
  This bracket mounts using factory holes on the side of the engine block, which may be occupied by accessories like air conditioning brackets or other components. It is not compatible with setups where these mounting points are already in use.
  Please refer to the product images to ensure compatibility with your build.

The trigger wheel / front damper pictured is not included within this kit, it is only there for visual reference.
