The term 'heavy duty' applies to much more than just the massive turbodiesels that wear the HD badge. Every aspect of the automotive world experiences some form of heavy-duty activity. From the giant mechanical turbodiesel beasts, low-slung sports cars, and off-roading machines to hatchbacks, family haulers, and grocery-getters, heavy-duty heat is universal. Luckily, we here at Mishimoto have devised a heavy-duty means of managing that heat.
For anything to be dubbed "heavy-duty," it needs to do two things. It needs to keep the fluid running through the core cool under the most grueling conditions and be able to take a beating at the same time. Performance and durability are absolute musts for a heavy-duty cooler. In this case, these two characteristics are intertwined.
