Frequently Asked Questions
SKU: MHX-245
Improved Racing's Motorsport Heat Exchanger (MHX) series oil coolers are the result of several years of development and testing to create a highly efficient oil cooler. These coolers were perfected through extensive testing on our in-house heat exchanger test system and wind tunnel.
The MHX-245 oil cooler is a universal version of our MHX-245C oil cooler used in our C6 Corvette oil cooler kits. This triple-pass oil cooler surpasses the heat rejection rates of larger, heavier stacked-plate coolers made by brands such as Setrab, Mocal, and Earl's. Compared to a 72-row, 4.5" wide core stacked plate cooler, this cooler is 12% smaller overall and 9% lighter, yet holds more fluid volume. The core is 23% thinner and has a lower row and fin density, allowing more air to flow through the cooler to other heat exchangers (such as a radiator) behind it.
A major design focus was to minimize welds and brazings to make these coolers stronger, lighter, and less prone to leaks. All four end caps are single-piece CNC-machined billet aluminum. The rows consist of laser-welded, thin-gauge aluminum tubes stuffed with turbulators to maximize heat transfer while minimizing weight. The triple-pass design with long end-tanks maximizes heat transfer efficiency while maintaining a low pressure drop across the cooler.
There are four M8x1.25 mm mounting holes, one near each corner of the cooler. Improved Racing has designed mounting brackets (sold separately) to make mounting your cooler as easy as possible. The brackets feature integrated rubber isolators that protect the cooler from excessive vibration and extend the life of the cooler.
The MHX-245 cooler features -10AN male ports on the same side of the end tank for convenient line routing. This cooler is designed to be mounted horizontally and is a great fit in the grill location of most vehicles.
All Improved Racing oil coolers are pressure tested to 175 PSI to ensure no leaks and are rated for continuous operation at 150 PSI. Our coolers are made in the USA and backed by our Lifetime Warranty.
