The latest in core design and manufacturing techniques results in the lightest and most efficient cooler available for your E46 M3.
Even in stock trim, the oil in the E46 M3 gets hot. Add additional horsepower and stress the engine by running it around the track for 10 minutes straight, and the oil gets very hot. Even the best synthetic oils should be kept under 250 degrees if possible, and the oil should never get above 300 degrees. On an E46 M3, the stock cooler just won't get the job done.
We've partnered with C&R Racing, the leading US manufacturer of cooling systems for the Motorsport industry, to bring you the best E46 M3 replacement cooler on the market. Filled with features, this piece just plain works.
The cutting edge core design, courtesy of PWR in Australia, allows this stock-sized and stock-mounted cooler to outperform its OE counterpart by almost 30% while only weighing 2.6 lbs, or a little less than half!
Available in stock-style hose-mounted version only. Compatibility with AN plumbing will require the use of our Oil Cooler Fitting Kit, which is sold separately. Mounts below radiator using the stock plastic shroud.
Core made in Australia. Manufacturing of end tanks and tubes and final assembly performed in the USA.
