Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.
Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.
Kit contents:
Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)
Low temp thermostat spring

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter. Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon". The lines and cooler are pressurized, but oil does not flow through them. Flowing oil means it is being cooled and not just acting as an external reservoir.
Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing. This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.
