Upgrade your BMW N54 turbo oil return with the RB BMW N54 High Flow Oil Drains. These performance oil drain lines are engineered for efficient, reliable turbo oil draining on all stock frame style N54 turbos. If you are chasing power, solving turbo smoking issues or future-proofing your build, these high flow oil drain lines deliver consistent, unrestricted oil return from the turbo to the sump/oil pan. Designed for the N54 engine in E82 135i, E90 E91 E92 E93 335i, E60/E61 535i, E89 Z4 35i/35is, E71 X6 35i and F01/F02 740i, the RB04 drains are a proven upgrade that improves reliability and helps prevent oil backing up in the turbo core.
Why upgrade your N54 turbo oil drains
OEM N54 oil drain lines can kink, collapse internally and restrict flow, especially after servicing or with age. Varying and undersized inner diameters reduce oil return capacity, which can lead to turbo smoking, leaks and poor draining. RB High Flow Oil Drains solve this with a straight, direct flow path and a consistently large inner diameter for optimised draining, improved reliability and better performance on both stock and upgraded turbos.
Key features and benefits
- Straight flow path from turbo outlet to sump/oil pan for maximum oil return
- Consistent large inner diameter to prevent restriction and improve drainage
- Optimised draining helps reduce turbo smoking caused by restricted OEM lines
- Designed for all N54 stock frame style turbos including RB, Pure, VTT, Hexon and OEM
- Ideal reliability upgrade for tuned and performance-modified BMW N54 engines
