Clutch Flywheel/Pressure Plate
This Pressure Plate is made by the OEM supplier Sachs and equivalent to the BMW supplied part in every way. It's essentially the flywheel ring gear, pressure plate and diaphragm spring, all in one and it is one of two main components that should always be replaced when the clutch disc is replaced.
Whenever you replace your clutch disk, it is imperative that you also replace this part to ensure that you get the longest life and best performance out of your clutch. Also replace the Housing Cover at the same time!
This part is identical to BMW Part Number 21 21 7 702 595
