The Lexus IS-F runs very high oil temperature under track or aggressive canyon road conditions (same issue with the new IS500). That is why Lexus added an auxiliary oil cooler to the RCF. Running an oil cooler at the track will improve the reliability, durability, and longevity of your engine by reducing oil temperatures, ensuring that your oil maintains adequate viscosity to protect vital engine parts such as bearings and piston rings.
Product specs:
- 25 row Setrab or Koyo oil cooler
- Mocal 185F thermostatic sandwich plate

Clayton Miller: "I just ran my first track event after installing your oil cooler and USRS on my ISF and what a difference!! My ISF ran Much cooler (never overheated) and the USRS made it a lot easier to get around the corners of the road course at AutoClub Speedway. I was able to get my lap times down to 1:56.6, a time I thought I would never achieve in this car!! It is so nice to be able to find aftermarket products like this that are made from someone that actually goes to the track with their ISF as I do, Thank You!"
