KOYO Koyorad HH012170 Lexus IS-F Racing Radiator




Koyorad is pleased to introduce an all-aluminum performance radiator for the 2008-2011 Lexus IS-F.  This is a Race Use Only radiator featuring Koyorad’s 48mm two row, high density “Hyper” core which will bolt to the factory equipped fan shroud.   In order to increase the overall cooling performance and eliminate the possibility of contamination between the engine coolant and transmission fluid, the heat exchanger found in the OEM radiator has been removed.  Users are required to provide and install a secondary transmission cooler to supplement or replace the factory equipped auxiliary transmission cooler.   Koyorad’s superior quality, precision hand welds, reliability and uniformity are what have earned Koyorad their excellent reputation in performance radiators worldwide.



Radiator Features:

  • High Density Hyper Core
  • 48mm Thick
  • Two Row
  • Direct Fit with OEM fan Shroud
  • Billet Drain and bleeder plugs
  • Race Use Only (Requires transmission cooler, not included)
  • Triple Pressure tested
