The results are in and they are exactly what we expected! This cooler provided huge gains in cooling efficiency. Let’s take a look at the data we compiled. First up is the core volume comparison.
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.

Welcome to our third installment of the build! We are nearing the completion of this project, with only some final test fitting necessary and data collection to ensure that this product performs to our standards. First, take a look at the Mishimoto oil cooler compared to the stock unit.

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!

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
