    Time to see if this cooler can make a significant impact on fluid temperatures. As before, we borrowed a test fit vehicle from the folks over at Open Road Tuning.

    Our team now had a functioning oil line adapter to convert from the stock oil filter housing to -AN fittings. Now we would be able to move forward with designing the actual heat exchanger for our kit. We reached out to a few of our local friends and sourced this Oxford green example!
