N55/Vargas Turbo Coolant & Oil Line O-Rings, BMW - 135i/M235i/335i/435i/535i

These are the o-rings for the turbo coolant and oil lines on the N55 turbo. These o-rings should be replaced when installing a new turbo, such as the Vargas performance upgrade on 2011+ E82 135i, E9X 335i, F22 M235i, F30 335i, F32 435i, or F10 535i with the N55 engine.

Included in this turbo install package:
2 x Genuine BMW oil line o-ring (11427590576)
2 x Genuine BMW oil line o-ring (11427590577)
3 x Genuine BMW coolant line o-ring (11537590575)

O-rings should be replaced anyway as they tend to leak over time. Since the lines will be moved from your old turbo to the new one, this is the perfect time. We include o-rings for the line connection to the block as well.

All of these o-rings are Genuine BMW parts with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
