When your A/C starts blowing warm air, making a horrible grinding noise, or locking up the auxiliary belt entirely, you need a replacement compressor you can trust. Cheap aftermarket A/C pumps are notorious for leaking gas or suffering premature clutch failure. We stick to genuine OEM units so you can do the job once and do it right.

This is a genuine BMW air conditioning compressor (manufactured by premium OEM supplier Denso, model 6SAS14A), carrying the BMW part number 6452 9299328-05. We’ve pulled this directly from a running B47 engine. It comes supplied exactly as pictured, completely assembled with the ribbed drive pulley and original mounting bolts still seated in the housing.

Before hitting the shelf, every compressor is checked on our Coventry workbench. We manually spin the drive pulley to ensure the internal bearings are smooth and free of gritty resistance or excessive play, and we verify the aluminium housing is free from crash damage. It’s a proper, heavy duty replacement ready to be bolted up and re-gassed.

Direct Fitment: designed specifically for the BMW B47 engine architecture.

Inspected Quality: pulley bearings checked for smooth rotation and housing checked for integrity.
