Cooler Heads Prevail

Keep your MKIV Supra running cool under pressure with the PHR Aluminum Race Radiator. With a 2" thick core, TIG-welded aluminum construction, and optional -20AN fittings, it's built to beat the heat on the street or track. Plug-and-play fitment means serious performance with zero hassle.

New for the Race Radiator: Internal Transmission Cooler

We’ve taken the performance even further with an integrated internal transmission cooler — 50% larger than the OEM unit!

This delivers outstanding transmission cooling, eliminating the need for an external trans cooler in most builds. Perfect for built A340E, TH400, or Powerglide automatics, and street/strip setups running serious power.
