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.
A major design focus was to minimize welds and brazings to make these coolers stronger, lighter, and less prone to leaks. 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 core is 23% thinner than typical stacked plate coolers 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. Overall, these coolers are lighter and more compact than stacked plate coolers from other brands, while providing similar heat rejection rates.
All coolers feature M8x1.25 mm mounting holes. Improved Racing has designed lightweight 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.
Most coolers feature -10AN female O-ring boss ports on the same side of the end tank for convenient line routing. Optional fittings are available in -6AN, -8AN, -10AN, and -12AN JIC male flare threads. The MHX-248 and MHX-248C coolers feature male -10AN JIC flare ports welded to the cooler.
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.
CNC-machined billet aluminum tank end caps with machined mounting holes on all four corners
