Koyo 93-95 Mazda RX-7 1.3L Turbo N-FLO (Dual Pass) Radiator - HH060644N

Koyo 93-95 Mazda RX-7 1.3L Turbo N-FLO (Dual Pass) Radiator – HH060644N

The Koyo HH060644N is a race-proven N-FLO dual pass radiator engineered for the demanding cooling needs of the third-generation Mazda RX-7. Designed specifically for 1993-1995 FD3S models with the 1.3L turbocharged rotary engine, this radiator features an internal partition that routes coolant through the core twice before returning to the engine, dramatically improving heat dissipation compared to traditional single-pass designs.

Built with a 48mm all-aluminum core and high fin density, the HH060644N provides exceptional cooling capacity to keep rotary engine temperatures under control during spirited driving, drifting, or extended track sessions. TIG-welded end tanks and Nocolok-brazed construction ensure maximum durability and reliability under extreme conditions. The direct-fit design retains all factory mounting points, works with OEM hoses and fan shroud, and requires no modifications for installation.

If you’re pushing your FD on the street or at the track, the Koyo HH060644N delivers the cooling performance and reliability your 13B needs.
