Finally, the results are in! The testing of our 2010-2012 Cummins Performance Intercooler is complete. After months of development and weeks of testing, our team was extremely excited to crunch the numbers to see how our cooler compared to the stock unit. Before we jump into the actual data pulled from our dyno pulls, we will first compare the physical attributes of the Mishimoto cooler to the stock unit.

Intercooler Physical Comparison

First, our comparison of overall thicknesses of the stock and Mishimoto cores. This difference was displayed in an earlier post where we showed the actual measurements.

Alright, it is finally time to see how our engineering team did with the development of this product! First, we measured the physical properties of the Mishimoto radiator compared to the factory radiator. Our first chart highlights the most common selling feature of a performance radiator: core thickness.

Mishimoto vs. factory radiator core thickness

We squeezed out as much additional core thickness as possible without causing any fitment concerns with factory

Time to install our prototype radiator into a test vehicle to make sure that it fits perfectly. Luckily, we were able to check fitment on the same donor vehicle we used for our last round of testing. Once the truck rolled into the shop, we quickly installed our prototype radiator shown at the end of our last post. Check out a few shots taken during the installation process!

Time to design an intercooler! Our first step toward this goal was to remove the intercooler so we could collect all the data points we needed. All front-end components were then removed from the truck to provide access.

Many of you may be following our other write-up regarding the development of our intercooler for the 2010-2012 6.7L Cummins. Along with designing and testing an incredibly efficient intercooler, we also worked to improve the engine cooling efficiency by crafting a performance aluminum radiator. A typical enthusiast may be wondering, why would I want to upgrade my radiator? Couldn't I spend that money on modifications that make my truck faster, louder, and more fun? Possibly, but keep in mind the benefits of an aluminum radiator upgrade. First, the improvement in reliability is a huge factor for many of our consumers. The factory radiator is constructed from an aluminum core mated to plastic end tanks. The connection point uses a rubber gasket which is then
