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, CSF parallel flow condenser, R134a expansion valve, new R134a lines (inside and out), 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 model/year should I choose?
Use the mfg. date on the driver's door of your E30 as well as our supplemental user guide to select the appropriate combination for your car.

Which condenser and fan should I choose?
For a complete and proper conversion, we strongly recommend using our high-performance CSF parallel flow condenser and SPAL fan combo for the most efficient A/C system. If you are planning to use your original fan, we recommend using the Nissens condenser. 

Do I need to replace my interior lines?
While your original R12 lines can be used, it's highly recommended to replace all rubber lines when converting to R134a to prevent against leaks.

What if my E30 didn't come factory with A/C?
Our products are designed to support factory A/C models; however, to fit them into non-A/C applications you will need to obtain a factory HVAC wiring harness, high-pressure drier return line (64531381740), evaporator (64518391780), aluminum engine accessory bracket (64521717007), and factory interior HVAC box with sensors, control module, thermostat, etc. Additionally, we recommend replacing your OEM hardware with our A/C bracket and hardware kit.

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. It is designed to fit both stock and euro headers while providing ample clearance around the factory oil cooler 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.
