H SERIES 48mm Core Thickness

Built with a robust 48mm core, the H-Core Series is engineered to offer excellent cooling when space is an issue. Increased capacity means better cooling reserve when you need it. Intended for both circuit and daily use, some systems may double your coolant capacity and see up to 35% increased performance over your stock radiator. Unless noted otherwise, all Koyorad H-Series all Aluminum radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans. See notes in individual item descriptions for details.

The KOYO H-Series – 48mm core radiator provides improved cooling coverage for both street and track applications.

Construction is held to tight quality control standards that are illustrated in the outstanding Heliarc soldering, pristine tube and fin alignment, and mirror-like surface finish. The tubes, fins, headers, and brackets are brazed in a state-of-the-art Nocolok furnace, which bonds these components into a virtually indestructible radiator unit.

All fan mounts are situated to OE specifications, and using the OEM mounting locations facilitates fitment into the RX7 FB Series 3.
