Mishimoto Ford Focus ST Oil Cooler Kit

With a solid cooler mounting location in place, it was time to hit the road and collect some much needed data. In the past, we’ve had great results with our oil cooler kits in terms of temperature reduction, so we have no reason to believe this kit would perform any differently.

Testing Setup and Conditions

Before jumping in the car, we needed to set up our data collection equipment. We use AEM software and sensors to record temperature data for our oil cooler kits. We also use inline pressure sensors to ensure that we are retaining factory-like pressures.

Recording the stock system was easily done with our NPT sandwich plate adapter, as shown below.

For the testing of our liquid-to-air setup, we use sensors installed inline on our braided stainless steel line. This allows us to collect temperatures both before and after the cooler. Do note, we are using our non-thermostatic sandwich plate for testing purposes to eliminate the variable of temperature decreases being limited to our activation temperature.

Below, Steve is setting up the software for our runs!

Testing Conditions

  • 10 minute highway cruise at 65 mph
  • Special attention given to traffic in front of the vehicle to ensure fresh airflow to the vehicle
  • AEM AG-1 Data Logger
  • Ambient temperature range: 78°F–80°F

This test is completely repeatable and provides a nice baseline in terms of cooling performance.

Results!

Time to see how we did! Check out the plot below showing a comparison of stock temperatures with the data from our oil cooler system.

Our cooler setup provided some very nice decreases in fluid temperature. The stock oil system regulated fluid temperature at right around 200°F–205°F during the highway cruise. With the Mishimoto system, things were a bit different. The temperatures exiting the engine started at around 190°F and quickly dropped, settling in the neighborhood of 180°F–185°F. Fluid exiting the cooler for reentry back into the engine hovered in the neighborhood of 170°F. This is a temperature drop of around 30°F during just normal driving.

Although this is not track data, we can infer that our system makes a significant impact on fluid temperatures. On the track, we can expect similar efficiencies that will translate to substantial drops compared to the stock setup.

One more thing to note. We mentioned this testing was compiled with our non-thermostatic sandwich plate. If we had been utilizing our thermostatic unit, outlet temperatures would have hovered at the activation temperature (185°F) instead of dropping to 170°F.

Product 3D Models

We wanted to spice up the appearance of our mounting bracket. After playing around with a few different designs, we settled on the one shown below.

As you can see, we have incorporated the grille design into our bracket. Pretty slick stuff!

  1. I can’t wait to have this for my track days in Denver. The thin air here is making the car overheat really quickly. Also waiting on that OCC!

    1. Thanks Mike! Be sure to check our forum post on Focusst for details regarding our discounted pre sale. We are planning to launch that early next week and ship them out the last week of June.

      I am very confident the lower temperatures will keep your ST in check on the track!

  2. Ran a few track days at High-plain Raceway and Pueblo Raceway in Colorado and unfortunately engine oil still overheated. But was able to get a few more laps over the other ST’s
