BMW E46 328i/Ci Oil Separator Kits

Over time, it is common for the BMW E46 328i/Ci to develop weak spots in the rubber and plastic components, making them prone to clogging, cracking, or bending - leading to performance loss.

ECS Tuning has developed two kits to help take care of one of the most common areas to suffer from these symptoms.

A very poorly functioning Oil Separator Hose can let small amounts of water into your system, leading to freezing in the winter time. ECS kits will give you a complete refresh on parts that can become clogged from years of oil vapor running through.
