A/C Solutions BMW E28 Complete Conversion Kit

New for 2025! 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, CSF parallel flow condenser, R134a expansion valve, new R134a lines, and all the necessary supporting brackets. This upgrade will result in colder A/C vent temperatures, less strain on the engine, and a more efficient and durable A/C system. Which condenser and fan should I choose? For a complete and proper conversion, we strongly recommend using our new high-performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. However, if you are planning to use your original condenser and fan, select the "None" option. What if my E28 didn't come factory with A/C? Our products are designed to support factory A/C models; however, they can be fitted into non-A/C applications, but you will need to obtain a factory HVAC wiring harness, both interior lines, evaporator, aluminum engine accessory bracket (to mount our compressor bracket), and factory interior HVAC box with sensors, control module, thermostat, etc. Note: BMW 528e coming end of Q2 2025! What’s in the box?

Models fitted with fuel coolers will have to be capped and removed. For the 533i, BMW engine accessory bracket 64521284953 will be required to support the Sanden compressor bracket and the new lines cannot be used with the factory condenser. For the 528e and 533i, the late model condenser cover 51711929356 will be required to clear the CSF condenser. Images may not reflect all configurations of this product. 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 4-6 hours by a professional or at home without a lift. It is designed to fit both stock and euro headers while providing ample clearance around the factory oil lines and OEM brake ducting/undertray. This kit assumes your vehicle is stock and still retains all original equipment. Proper functionality of the evaporator, wiring harness, system electronics, and HVAC sensors is/are required for a fully functional system.
