Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade to the A/C system in the E28 to R134a using a modern Sanden compressor, larger parallel flow condenser, new R134a lines, and all the necessary supporting bracketry. This upgrade will result in colder A/C vent temperatures, less strain on the engine, and a more efficient and durable A/C system.

Note: Early model cars will need the later engine bracket(s): 64521717007 (M20); 64521284953 (M30). And late model cars with fuel coolers will have to be capped and removed.

What’s in the box?

  • Sanden SD5H14 (508) compressor
  • ACS compressor bracket
  • Parallel flow condenser (for use with OEM fan)
  • Low-pressure suction line (bulkhead to compressor)
  • High-pressure discharge line (compressor to drier)
  • High-pressure drier return line (condenser to drier)
  • OE filter drier
  • Continental v-belt
  • Compressor mounting hardware
  • R134a engine bay o-ring kit
  • Detailed installation instructions (download)

This product requires no R&D, and is easily reversible using professionally engineered components, OEM-like hardware, and durable replacement parts resulting in a trouble-free installation that can be completed in under 4 hours by a professional. It is designed to tuck neatly under the rad cover while providing ample clearance around the factory oil cooler and OEM brake ducting/undertray.

This kit assumes your vehicle is stock and still retains all original equipment. If you have aftermarket headers, please contact us before ordering. It is designed to use the OEM aux fan, high-pressure switch (on drier), and high-pressure drier return line, along with proper functionality of the evaporator, expansion valve, and HVAC sensors.
