Part # MHX-248C

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-248C oil cooler is the cooler used in Improved Racing's C5 and C6 Corvette oil cooler kit. Note that this cooler does NOT work with the factory C6 Z51 and Z06 oil cooler lines. It requires aftermarket -10AN oil cooler lines and an oil cooler adapter. If you need a complete kit, see Improved Racing's C6 oil cooler kit, part number EC6-600.

The mounting bungs on the ends of the cooler bolt to the factory mounting locations in the radiator shroud for easy installation. The four mounting bungs on the ends of the cooler are threaded for M8x1.25 mm screws. 

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 4% 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. 

The MHX-248C cooler features -10AN male ports on the same side of the end tank for convenient line routing. 

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. 

Features and Benefits

  • Compact, lightweight design is 12% smaller, 4% lighter, and has 104% more fluid capacity than a 72-row, 4.5" wide core stacked plate oil cooler.
  • Surpasses heat rejection rates of larger 72-row stacked plate oil coolers.
  • Triple-pass design to maximize efficiency.
  • Higher pass-through airflow rate than stacked plate coolers.
  • -10AN male ports on same side of end tank.
  • 4x flanged M8 mounting screws are included.
  • Lifetime Warranty.
  • Made in the USA.

Applications and Fitment

  • 2005-2013 Chevrolet Corvette (C6), all models
  • NOTE: Requires aftermarket oil cooler lines and oil cooler adapter, or use Improved Racing's complete bolt-on oil cooler kit (see part number EC6-600)
