Thermostat Temp:

Now includes our larger, custom-built, triple-pass oil cooler for even better cooling. This cooler is lighter, allows more air flow, and has more oil capacity than the cooler we previously used.

Improved Racing's bolt-on oil cooler kit adds massive cooling capacity to the C6 Corvette. Oil temperatures in track conditions often reach as high as 300°F with the factory Z06 oil cooler setup. This kit will lower peak oil temperatures by as much as 30-50°F.

This kit is not only essential for track use, but also perfectly streetable thanks to the built-in oil thermostat, which allows engine oil to reach safe operating temperatures much faster than the factory oil cooler system.

The chart below graphs oil and coolant temps with the factory setup compared to the Improved Racing 180°F thermostat setup after a cold startup. As you can see, in cool weather (50°F ambient), oil temps never go above 120°F with the factory oil lines, even after over 20 minutes of warm up time!

With the Improved Racing thermostat installed, oil temps are allowed to increase to safe operating temperatures, even with the much larger oil cooler included in this kit. Note these temperatures were logged using the sensor at the bottom of the dry sump oil tank, which reads lower than the temperature at the oil thermostat.

The kit includes professionally assembled, lightweight -10AN oil lines featuring a Viton rubber interior, stainless reinforcement to prevent kinking, and a silicone-fiberglass sleeve for protection from header heat.

The thermostat is available in three temperature ratings, 180°F, 200°F, and 212°F. The 200°F and 212°F units are recommended for racing applications where a higher oil viscosity is used. The 180°F unit is recommended for street use.

I installed this kit on my C6Z track/race car. Fit and fitment is superb. Installation was very straightforward and all parts, lines and fittings are of extremely high quality. My car is a dedicated track/race car with full aero, suspension and is raced on Hoosiers or slicks, often times in extended, abusive conditions. The oil temps immediately dropped 25-30 degrees after I installed the kit. The oil now stabilizes around 260 degrees, compared to 290 degrees+ prior. This has allowed me to run a more proper viscosity oil for the bearings and motor and lets me push the car far, far longer. The coolant temps have dropped as well. I no longer have to worry about the oil temps spiraling out of control. Additionally, with the added thermostat, my oil temps come up to proper operating temperature MUCH faster. And finally, the service I received both before, during and after my purchase was very professional, polite and intelligent.

I am extremely pleased with this oil cooler. I was expecting maybe a 10 degree improvement in oil temp but I was seeing consistently 20 - 30. On hot days (93-94 degrees) outside my stock oil cooler was letting the oil get to 290-295 degrees and I started to back off to cool things down. With the EC6-600 I was driving hard the entire time. It was usually staying at 250 degrees but once touched 260 before dropping back to 255 degrees. I was in 91 degree weather and eventually quit watching my oil temp gauge and switched over to my front tire pressures. I even had someone in the car for an evaluation that runs racing Z06s that said he was impressed with my oil temp.
