Mishimoto Ford 6.0L Powerstroke Coolant Filter Kit

Project Introduction

Factory 6.0L engine bay

The Ford/International 6.0L was launched in 2003 in an effort to compete with the high power output from the GM 6.6L Duramax, while still meeting new emissions standards. In factory form, the 6.0L Powerstroke is generally reliable and will perform a majority of the tasks demanded by truck owners. Unfortunately, as many have discovered, increasing the power output on the 6.0L produces increased stress on the cooling system,

Product Testing and Procedures

The fun part of development is the reveal of our initial prototype design, but the truly exciting part is the testing portion of development. At this point our offices are disrupted by noise from the dyno pulls, tempting a few of our empolyees to filter into the garage and check out the action. Below we see the truck loaded onto the dyno.

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.

Prototype Test Fitting

Time to see if this massive intercooler fits! Our prototype design was based on critical dimensions taken from a test vehicle so we could expand the cooler as much as possible without causing fitment concerns. Let's see if we succeeded on our first attempt!

The radiator and intercooler are thicker than the factory units, so we bolted the intercooler prototype to the new Mishimoto radiator prototype. Now attached to each other, we installed them together for the benefit of those customers who would want to purchase both components.

Prototype 3D Design

Now that we outlined our project goals and had all the test data from the factory intercooler, our engineers were ready to design a prototype intercooler. Using dimensional data from a rendering of the truck as well as the actual measurements we took from the test vehicle and factory intercooler, our team was able to create a very nice looking prototype. Check out a couple renderings of the design!

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

Welcome back! In our last segment we removed the factory intercooler so we could determine if this project would even be necessary. The good news is, all that work was not for nothing; our team found several aspects of the factory intercooler that could be improved. Check out a few more detailed images of the factory intercooler.

First, a peek at that interesting metal end tank we discussed in part 1 of this article.
