Product Description
This oil cooler kit is designed as a complete bolt-in fit, requiring no modification to work with the stock radiator or the Mishimoto BMW E46 Performance Aluminium Radiator. To ensure a complete direct-fit, Mishimoto engineers have designed a fully CNC-machined 6061 aluminium and 303 stainless steel BMW E46 Oil Line Fitting Kit, which makes the removal of the stock hard lines and installation of stainless steel braided lines a simple task.
This kit includes pre-assembled stainless steel lines with -10AN fittings to help direct the oil to and from the cooler, as well as a black Mishimoto Oil Line Stay to keep your lines from rubbing. As with all our products, the Mishimoto E46 M3 Oil Cooler Kit includes the Mishimoto Lifetime Warranty.Please note: Mishimoto fully inspects and cleans all products prior to packaging. However, it is recommended that customers flush the oil cooler with one quart of clean oil prior to installation to remove any debris accumulated during shipping. Please feel free to contact us at support@mishimoto.com if you have any questions.

Time to see if this cooler can make a significant impact on fluid temperatures. As before, we borrowed a test fit vehicle from the folks over at Open Road Tuning. Once we had the car on the lift, we removed the factory cooler lines and spliced our temperature sensors into the stock lines so we could collect inlet and outlet fluid temperatures.

Our team now had a functioning oil line adapter to convert from the stock oil filter housing to -AN fittings. Now we would be able to move forward with designing the actual heat exchanger for our kit. We reached out to a few of our local friends and sourced this Oxford green example!

Our friend Andrew at Open Road Tuning was kind enough to loan his vehicle for a week of development! First we tore off the stock cooler to get a look at what kind of space we had to work with.

The BMW S54 won the "International Engine of the Year" award at its inception in 2001 and was consistently on "Ward's 10 Best Engines" list for four years. It's hard to argue against the E46, an 8,000 rpm, 3.2L straight-6 producing over 330 hp and 260 ft-lb of torque, with a competent chassis, an exhaust note that straightens the neck hair of all within earshot, and a body styling that is unmatched in uniqueness. Although my opinion is slightly skewed, being a fan of most BMW products, many would agree that the E46 was a fantastic vehicle for the street and even better for the track. E46 M3 pricing has trickled downward over the past few years, meaning that even those on a tighter budget can find their way into the cockpit of one of BMW's finest. We are seeing these vehicles at track
