High-performance vehicles require large oil coolers to ensure the oil does not become overheated during strenuous use. These coolers also introduce the danger of over cooling the oil and delaying engine warm-up, resulting in horsepower loss, excessive engine wear and reduced gas mileage. Oil thermostats perform the critical function of bypassing the oil cooler until the oil has reached its minimum operating temperature. Improved Racing's oil thermostat is a 100% bolt-on solution to mounts to the oil pan just above the oil filter. The thermostat maintains a minimum oil temperature of 180°F (82°C) +/- 5°F in most conditions. The compact design clears most headers. It features female -8AN O-ring boss threads and is available with fittings for -8AN, -10AN, and -12AN lines. This adapter can be mounted upside down on the 5th generation Chevrolet Camaro / Pontiac G8 oil pan for additional knock sensor clearance.
