The rubber hoses and oil separator can crack or become faulty, leading to vacuum leaks or oil leaks. This is caused by the stress the components are exposed to during heating and cooling cycles, especially if the vehicle is not brought up to operating temperature during driving in cold weather climates.

This kit includes the needed hoses, oil separator, and hardware.

Fits the following BMWs:
