MHX-206 High-Efficiency Oil Cooler
Couldn't load pickup availability
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-206 "Baby" oil cooler is an efficient, single-pass cooler ideal for power steering, differential, and transmission fluid cooling in a very compact space. It's also ideal for oil cooling on small engines such as motorcycles, ATV's, go karts, etc. The MHX series coolers are smaller, lighter, and have more fluid capacity than stacked-plate style coolers of similar performance.
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.
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 and a single-pass design to minimize pressure drop. 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.
CNC-machined billet aluminum tank end caps with machined mounting holes on all four corners
