Oil Thermostat Delete

A great way to reduce oil temperatures while on track. This thermostat delete fits in place of the factory oil thermostat and provides full flow of all the oil coming out of the pump through the coolers. With the factory unit, full flow is never achieved, some is always diverted back to the engine without any cooling.  

Compatible with any E46 M3 S54 engine, or any M50, M52, M54, S50 or S52 running a Euro Style S50 oil filter housing, which has ports for routing the cooler hoses directly to the engine.
