BMW N55 Lubrication System Conversion to S55 Twin Pick Up Sump Kit

Safeguard your 3.0 turbo straight six on circuit and fast road with the factory S55 lubrication hardware adapted for N55 applications. This OE parts package brings the S55 twin pick up wet sump and scavenge arrangement to your F series N55, delivering consistent oil supply, excellent pressure stability and confidence during sustained lateral G, heavy braking and long sweeping corners.

We have installed this conversion on our own builds and across many customer cars and the results have been brilliant. Track day regulars, time attack enthusiasts and spirited drivers choose this setup for rock solid oil control, reduced surge risk and OEM fit and finish. It is genuine BMW hardware taken from the S55 platform and configured to suit N55-powered models for dependable lubrication under hard use.

Key benefits

• Twin pick up sump layout that keeps the pump supplied during high G manoeuvres
• Revised main pump and scavenge stage to move oil where it is needed and reduce aeration
• Baffle plate and windage tray to manage slosh and help maintain a stable oil column
• All components are OE BMW for perfect fitment, long term durability and peace of mind
• Ideal for track days, fast road driving and endurance style use where temperature and G loading are elevated
