Improved Racing’s low-profile oil cooler adapter bolts directly to the factory GM LS oil pan and features a built-in thermostat. The angled front cutout and a maximum thickness of just 1.30″ makes this unit slim enough to clear most headers.
Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. This unit’s built-in thermostat helps protect the engine by speeding up warm-up time and maintaining oil temperatures at optimal levels. The thermostat maintains a minimum oil temperature of 180°F (82°C) +/- 5°F in most conditions.
The adapter features an 1/8″ NPT port for an oil sensor or turbo oil supply. It’s machined from a single piece of 6061-T6 aluminum and is black anodized. The adapter features standard female -08AN O-ring boss ports for optional anodized adapter fittings for -08AN, -10AN or -12AN lines. The adapter can be mounted upside down on the 2010+ Camaro / G8 oil pan for additional header clearance.
Old part number EGM-1012.
