Mishimoto BMW E46 M3 Performance Aluminum Radiator
How do you go about redesigning a radiator to make it perfect for track use? After coming to the realization that our existing E46 M3 aluminum radiator was not performing as we would like for track-specific vehicles, our team determined it was time to take action. Our original product was designed some time ago, and our processes, material use, and overall attention to detail have significantly improved since then.
These days Mishimoto is spending huge amounts of time in R&D to develop effective and efficient cooling

Mishimoto BMW E46 M3 Performance Aluminum Radiator
Thanks to an absolutely miserable winter in the mid-Atlantic area (will it ever end?), we have been struggling to find weather warm enough to test our products currently in the development process. To provide accurate, real-world data for our line of cooling products, we are required to test everything at temperatures we expect our customers to experience under normal driving conditions. Testing an oil cooler on a 30°F day is going to provide wildly different results than on a 90°F day! To provide the most accurate data possible, we needed to modify our strategies and look beyond our norms. In this case, we traveled down to Orlando, Florida, to properly test our brand new E46 M3 radiator!
