Part # MHX-215

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-215 oil cooler is a dual-pass oil cooler that matches heat rejection rates of larger, heavier stacked-plate coolers made by brands such as Setrab, Mocal, and Earl's. This cooler is ideal for cooling transmissions, differentials, transfer cases, power steering, and small engines in a compact space. Compared to a typical 25-row, 4.5" wide core stacked plate cooler, this cooler is 16% smaller overall and 5% lighter, yet holds more than twice as much 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 dual-pass design also maximizes heat transfer efficiency. 

There are four M8x1.25 mm mounting holes, one on each corner of the cooler. Improved Racing has designed lightweight aluminum 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 200-series 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. 

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.
