The Lexus IS500 oil temperature runs very high under track or aggressive canyon road conditions (same issue with IS-F). This is the first product of its kind for the IS500 that combines an improved transmission oil cooler and secondary added engine oil cooler. This product builds on similar successful and proven products we have been selling for the IS-F for years.

Running these coolers at the track will improve the reliability, durability, and longevity of your engine by reducing oil temperatures, thus ensuring that your oil maintains an adequate viscosity to protect vital engine parts like bearings and piston rings.

Engine Oil product specs:

  • 25 row Setrab or Koyo oil cooler
  • Mocal 185F thermostatic sandwich plate
  • Genuine Mocal fittings
  • Genuine Mocal 12AN swivel fittings for maximum flow with no pressure drop
  • 12AN Stainless steel braided oil lines for maximum durability
  • All required brackets and hardware for installation
  • 15deg F reduction in oil temperature with Factory Oil cooler bypassed (yields ~5-8deg drop in coolant temps)
  • 30+deg F reduction in oil temperature with Factory Oil cooler retained.
The RR Racing Transmission cooler is a much better and cheaper alternative to the optional transmission cooler that Lexus offers only in the JDM market for the IS500. Our transmission cooler is a 25 row Koyo or Setrab cooler instead the smaller 8 row Lexus upgraded cooler.

All components in this product kit are proudly engineered and manufactured here in the United States of America.

Please note that this package is offered only for the IS500 as we do not recommend the transmission cooler for the IS-F without an upgraded radiator. Therefore, for the IS-F, we continue to offer the upgraded Radiator/Transmission package with a separate engine oil cooler.

Endorsements for many of our products keep growing! Every time a serious racer tries our products on the track, they get excellent reviews and endorsement.

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!"
