Improved Racing's thermostatic oil cooler adapters make it easy to add a performance oil cooler to your LS-family engine. The built-in thermostat automatically bypasses the cooler until safe operating temperatures are reached. No more worrying about over-cooling engine oil or long warm-up times!

This "bottom inlet" thermostatic oil cooler adapter is easy to install in the C5-C6 Corvette and 5th generation Camaro as it does not require adjusting the knock sensor to clear the oil lines. Unlike many other oil cooler adapters, it will also clear the LSX and Dart LS Next engine blocks without modification.

The thermostat block features an additional port which may be used for a 1/8" NPT or M12 sensor or as an oil feed for an oil accumulator or a turbo. For the C5 Corvette, choose the M12 sensor port option to retain use of the factory oil temperature sensor. The factory sensor will plug right in; no need to extend the sensor harness.

The adapter features standard female -08AN O-ring boss ports that accept optional male adapter fittings for -08AN, -10AN or -12AN lines.

Installation Notes
  • If equipped with a factory oil cooler, the following vehicles will require the optional factory oil cooler delete kit:
    • 2010-2011 Chevrolet Camaro SS & ZL1: Part # 22962571-KIT
    • 2012-2015 Chevrolet Camaro SS & ZL1: Part # HPL-1004-KIT
  • 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 on the IN port (part number DO-090-08-08 (-8AN lines) or DO-090-10-08 (-10AN lines). Note only one O-ring boss adapter fitting is needed when using this low-profile hose end.
  • Note: 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.
  • Rear-sump LS engine oil pans with factory-style oil bypass cover
