Product Description

The Koyo HH012170 Hyper Core aluminum radiator is engineered specifically for the 2008-2011 Lexus IS-F equipped with the 5.0L 2UR-GSE V8 engine and automatic transmission. Designed for high-performance street and track applications, this all-aluminum radiator significantly increases cooling capacity and thermal efficiency over the factory unit while maintaining direct-fit OEM-style installation.

Built around Koyorad's proven 48mm two-row Hyper Core design, the HH012170 improves heat dissipation during aggressive driving, track sessions, and high-temperature operation. The fully brazed aluminum construction and precision hand-welded end tanks provide exceptional durability under sustained thermal stress while retaining compatibility with the factory fan shroud and OEM coolant hose routing.

To maximize cooling efficiency and eliminate the risk of fluid cross-contamination, Koyorad removed the factory integrated transmission heat exchanger from this race-use radiator design. An external transmission cooler is therefore required for automatic transmission applications. With its increased coolant capacity, billet hardware, and direct bolt-in fitment, the HH012170 is an ideal upgrade for IS-F owners seeking reliable high-performance cooling performance.
