The C7 Corvette's water to oil heat exchanger is appropriate for a street car but is wildly insufficient for track or performance use. Those looking to delete the factory heat exchanger and replace it with a high-efficiency air to oil cooler can use Improved Racing's oil cooler adapter.

This adapter is recommended for track and performance use only, as it does not feature a thermostat. For street-driven cars, we recommend our thermostatic adapter, part number EGM-132.

The adapter features standard female -8AN O-ring boss ports that accept optional male adapter fittings for -8AN, -10AN or -12AN lines.

Two IN and OUT ports provide flexibility in line routing. Plugs are included for the two extra extra ports and an optional sensor adapter fitting may be used to accept an 1/8" NPT or M12x1.5 sensor. The extra ports can also be used for turbo oil feed lines or for plumbing an oil accumulator.

Features and Benefits

• 100% bolt-on in place of the factory heat exchanger, just above the oil filter
• Extra inlet and outlet ports can be used for sensors, turbo oil feed lines, or an oil accumulator
• Retains stock oil filter location
• Oil exiting the adapter is filtered oil
• 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish
• High-temp Viton seals
• Lifetime Warranty
• Made in the USA

Optional fittings available for -8AN, -10AN, or -12AN lines

Includes

• 1x Oil cooler adapter block for LT1/LT4 engines
• 1x Gasket, GM part # 12623359
• 2x Zinc-plated steel mounting screws

• Detailed installation instructions

Optional Add-Ons

• 2x Black anodized -8AN, -10AN, or -12AN adapter fittings with Viton O-rings
• 1/8" NPT or M12x1.5 sensor port adapter fittings

Installation Notes

• This oil adapter is designed for O-ring boss fittings with a straight thread length of 0.500" or less. We recommend using our fittings in order to guarantee proper fitment and seal.
• We recommend using a straight hose end fitting for the OUT port and a 90-degree hose end fitting for the IN port. For additional clearance, use our low profile hose end fitting, part number DO-090-08-08 (-8AN lines) or DO-090-10-08 (-10AN lines). Note that no O-ring boss adapter fitting is needed when using this low-profile hose end.
