Epic Motorsports S65 Oil Diverter Valve Kit - E9X M3

Convert your oil filter housing to full flow to reduce oil temps

The S65 engine in the E90/E92/E93 M3 has an internal thermostat that limits the amount of oil that flows into the cooler, even when warm! This thermostat is closed when the engine is cold so that the oil warms up quicker. But even at operating temp the thermostat does not open all the way! Or worse, can be stuck closed. E9X M3 owners who have experienced high oil temps at the track often don't have an explanation or solution - until now.

Includes diverter valve and installation instructions. The oil filter housing does not need to be removed from the engine, however access requires removing several items from the front of the engine - belt, fan, and power steering pump. This also provides a good opportunity for checking the oil filter housing seal for leaks.

This Oil Cooler Diverter Valve quickly remedies this issue by making the cooler full-flow. It diverts all oil through the cooler and lines for maximum cooling strategy. This will typically bring down stubborn oil temps 30+ degrees on tracked engines with the stock cooler. Once the housing is removed this is a quick 5 minute install into the factory S65 oil filter housing. This is not recommended for street cars without the addition of a performance inline thermostat. Drive conservatively and allow extra time for the oil to reach optimal temp (>150 degrees).
