The ECS Level 2 kit takes our Level 1 kit a step further. If you are ready to perform a truly complete oil separator system service, our Level 2 kit provides you with all of our Level 1 kit components plus a throttle body gasket, throttle body inlet boot, ICV grommet, and dipstick tube o-ring.
Our Level 2 Cold Climate kit includes the following:
Oil separator - BMW cold climate recommended
Hose from oil separator to dipstick tube - BMW cold climate recommended
Hose from oil separator to valve cover
Hose from intake manifold back to the connector hose
Hose from oil separator up to the intake manifold
Throttle body gasket
Throttle body inlet boot
ICV rubber grommet
Oil dipstick tube o-ring seal
It is highly recommended to replace the oil dipstick tube with the updated design by BMW as this also a common place for sludge to build up.
