EDO Performance & Tomioka Racing 2015 Subaru WRX: Engine Oil Cooler

So we have seen the 2015 Subaru WRX made 191whp and 225 ft/lbs from the factory and after re-flash using Cobb Accessport V3 the power jumped to 221 whp with 250 ft/lbs of torque on the dynapack dyno.  Next, we are installing the latest product from Tomioka Racing the temperature controlled engine oil cooler kit. The temperature- controlled oil sandwich adapter adds extra protection to the engine during cold climate with quick engine warm-up and kicks into operation when the engine oil is too warm.The Tomioka Racing cooler utilizes a SETRAB 16-row cooler core well known for its durability and performance. The Tomioka Engine oil cooler kit includes the thermostat adapters, AN8 stainless steel lines assembled with the aluminum fittings and the mounting brackets.

The compact core fits perfectly behind the front bumper beam and the limited ducting space behind the bumper beam fits perfectly for the AN8 stainless Steel lines. The cooler kit comes standard with the additional sandwich plate to accommodate the top-mount oil filter.

With the engine oil cooler installed, we test drove the car in normal street driving condition. The graph below shows the engine temperature difference before and after the installation of the oil cooler data-logged using the Cobb Accessport V3. The result is we saw a temperature drop of 14 degrees. Before the engine oil cooler installed, the engine temperature was at 210 degrees on average and after the oil cooler was installed the temperature average dropped to 196 degree.
