The MSW Oil Cooler Kit for E46 Non-M cars uses only the highest grade components and is a complete solution for your oil cooling needs. Oil coolers allow you to run the proper weight oil without worry. Great for sprint races, and nearly mandatory for endurance racing. Extend the life of your engine and improve its performance.
We’ve tried out numerous oil cooling solutions in our hunt for the best possible setup. We even have one of the last remaining and no-longer-available BMW Motorsport oil filter housing. What we’ve learned from years of racing the SpecE46 in the hot and humid South is that the S54/S50(euro) housing is the best solution for a clean and tidy package.
The MSW Oil Cooler Kit starts with a brand new S54 oil filter housing*. Then we remove the stock oil cooler thermostat and install a diverter valve to allow for full flow of oil to the cooler. We then add -10AN adapters to the housing to allow for easy installation of the cooler lines. Finally we modify the power steering pump mounting points to increase the strength of the mounting solution.
Our kit comes with already assembled Brown & Miller Racing Solutions (BMRS) PROGold Aramid brain AN hose with a high temp silicone heat sleeve over all the hoses. BMRS hoses and fittings are the top choice for pro racing teams around the world and are extremely light and durable. All lines are pressure tested before shipping and are compatible with all petroleum products.
The cooler itself uses a high quality Setrab heat exchanger with rubber isolated mounting points. You have your choice of two different sizes of coolers, depending on your needs.
Don’t worry about where to mount your power steering fluid reservoir, our kit includes a custom made bracket to locate the reservoir in the stock location. This means you use the stock power steering hoses with no modification. It also allows you to easily check and top off your steering fluid, unlike the S54’s normal location in a nearly impossible to reach spot.
Our included M12 to M14 banjo bolt is made of steel and zinc coated with a 1/8″ NPT threaded port on the end for easy addition of an oil pressure sensor. An included 1/8″ NPT plug ships with the kit if you do not need a sensor port.
Fits all E46 with M54B25, M54B30, and M52 engines.
