N5X/S5X Oil Filter Housing Relocation
BMW N5X Oil Filter Relocation & Cooling Simplification Kit
For N51 / N52 / N53 / N54 / N55 / S55
Have a race car or custom build, and want to relocate the oil filter housing — and simplify the cooling system at the same time?
This kit is for you.
Developed on our own N52-powered race car and inspired by factory E90 race programs of the past, this setup eliminates unnecessary complexity and gives you full control over oil and coolant flow.
By installing this plate:
You achieve 100% oil flow directly to the filter and cooler
You delete the factory water bypass that routes back to the OEM thermostat
You simplify the cooling strategy by controlling temperature via water pump speed, not bypass routing
Less plumbing. Less confusion. More control. Cooling System Simplified — The Right Way
This kit includes our redesigned “Mickey Mouse” fitting — but not the typical one.
Ours is:
A coolant block-off
Threaded for the coolant temperature sensor
Designed to convert the original cylinder head temp sensor port (the highest point on the head) into a bleed feed
Run that line to a remote expansion tank
Reduce trapped air and hot spots at the back of the head
Pair this with our Head Vent Kit for the ultimate solution in hot spot prevention on hard-driven N5X engines. Avaialble [HERE]
