BMW E30 Sanden Conversion Kit

Designed and engineered for the enthusiast, this conversion kit offers a complete, plug-and-play upgrade to the A/C system in the E30 to R134a using a modern Sanden compressor, parallel flow condenser, R134a expansion valve, new R134a lines (inside and out), 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: This product is not compatible with the M3, 325iX, or 318i/is, and models fitted with fuel coolers will have to be capped and removed.

COMING SOON (Dec '23): E30 M3 and 325ix
