This bracket is constructed from 1/8" steel and is powder coated for additional protection against damage from road debris. We overbuilt this unit to ensure longevity and optimal resistance against potential damage.

Check out the hardware we will be using to attach our housing to the bracket. This hardware is also powder coated to prevent corrosion.

Next, we assembled our filter housing, filter, and bracket together.

We then installed this system to ensure fitment on our test vehicle.

We mentioned in our 6.0L coolant filtration thread that we would be tackling the 6.4L as well. Let's take a look at some of the components our team has been putting together for the 6.4L kit.

Although the 6.4L does not seem to be as susceptible to buildups as is the 6.0L, a coolant filtration setup is certainly still a worthy investment in preventive maintenance.

So let's get started!

Filter Housing

We'll start with the filter housing. As mentioned in our 6.0L thread, we developed a housing with a wide range of adjustability that could be utilized for a variety of kits. This housing is shown below.

Here's a look at the hardware and filter mounted to this housing.

Our full prototype unit has arrived and is ready for some final test fitting! Before introducing our final product, let's take one last look at the stock hose setup.

Stock 6.4L radiator hoses

Now, check out the Mishimoto prototype kit!

Mishimoto prototype 6.4L radiator hoses

A few interesting things to note. First, we have replaced several of the bends that were previously plastic with our silicone hose. Instead of incorporating the bends into the quick disconnect fittings, we are using the hose to make all the bends.

Also, the stock hose uses a double O-ring connection on the engine-side quick disconnects. On the radiator side, the stock still uses a single O-ring system. We use double O-ring connections on both ends of our hoses for better protection against leaks and to reduce the chance of air entering the cooling system of

The Project Begins

Looking to pair your 6.4L aluminum radiator with a nice set of silicone hoses? We thought so! After developing a variety of components for the 6.4L Powerstroke, we decided to take a closer look at the radiator hoses on this truck.

After Ford released this truck in 2008, there were numerous complaints about leaking hoses. Ford issued a technical service bulletin (TSB) that offered a fix: a set of replacement hoses with an additional O-ring for better sealing power. This modification was made to the engine-side fitting of the hose, while the radiator-side still retained the single o-ring design. The replacement hoses seemed to solve the problem.

That said, the stock hoses still feature plastic quick-connect ends that lock into

With our testing complete, it was time to recap the results and see what kind of benefits our cooler was capable of producing. The testing procedures and information from our previous posts are outlined below.

Testing Procedures and Information

Vehicle: 2011 Chevrolet 2500 6.6L LML Duramax

Engine Modifications: None, all factory equipped

Ambient Temperature: 85°F (29.5°C)

Humidity: 35%

Sensors: PLX Pressure and temperature sensors were placed on both the hot-side and cold-side intercooler boots.

Physical Benefits

Before we jump right into the testing data, let's compare the physical aspects of our intercooler design that distinguish our unit from the factory cooler. We increased the core size of this cooler significantly, so let's take a look at the actual numbers behind the increase.

Comparison chart of intercooler volumes

The gains in

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.

To collect data, we installed our PLX sensors in a hot-side boot and a cold-side boot. We would be collecting both temperature and pressure data for each side of the cooler. Additionally, we would be recording power output to see if our cooler provides an increase in output.

Once we had everything set up, the dyno pulls began with the factory intercooler and the Mishimoto intercooler.

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.

Stock vs Mishimoto intercooler core thickness comparison

As seen in the chart above, we are doubling the thickness of the factory cooler. Due to the design and placement of the intercooler, AC condenser, and radiator, we were able to expand this unit

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!

When designing this intercooler, our team experimented with different end-tank diverters to provide better air dispersion through the core. Our goal is to spread the airflow to all portions of the core so we can take full advantage of the surface area available.

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 equipment. The factory core came in at just under 1.7" thick, while the Mishimoto radiator measures 1.95" thick, making the Mishimoto radiator 13% thicker than the factory radiator. This additional core thickness allows our product to provide a greater fluid capacity and promote improved efficiency, which is reflected in the following charts. Our second chart shows the improvements made in
