Extremely important on E36 Euro and S54 engines!
The factory oil cooler (found stock on E36 Euro M3 and S54 engines, also a common upgrade for others) have a thermostat that closes off the cooler path until the engine builds temp, then runs only a portion of the oilflow through the cooler once warm. Our Oil Cooler Diverter Valve quickly remedies this issue by making the cooler full-flow - or diverting all oil through the cooler for maximum cooling effect. This will typically bring down stubborn oil temps 30+ degrees on tracked engines, with the stock cooler.
5 minute install (once housing is removed) into the factory oil filter housing with oil cooler fittings. Not recommended for street cars without the addition of a performance inline thermostat.
A must have! From JR of Austin, Texas on 1/17/2012.
