Koyo 89-92 Mazda RX-7 1.3L FC NA/Turbo (MT) N-FLO Technology Radiator – HH060643N
OE fan shroud requires trimming for installation

The Koyo HH060643N is a high-performance N-FLO dual pass radiator designed for the second-generation Mazda RX-7. Built specifically for 1989-1992 FC models with the 1.3L naturally aspirated or turbocharged rotary engine and manual transmission, this radiator is engineered to deliver superior cooling performance for both street and track use.

Koyo’s N-FLO design uses an internal partition to route coolant through the core twice before returning to the engine, dramatically improving heat dissipation compared to traditional single-pass layouts. With a 48mm all-aluminum core and high fin density, the HH060643N provides excellent cooling capacity to keep your rotary’s temps stable under demanding driving conditions.

Precision TIG-welded end tanks and Nocolok-brazed construction ensure long-term durability and performance. While this radiator bolts into OEM mounting points, the factory fan shroud requires trimming for proper fitment due to the dual pass configuration.

Features:

• Direct fit for 1989-1992 Mazda RX-7 FC3S with 1.3L NA or turbo rotary engine and manual transmission

• N-FLO dual pass design for maximum cooling efficiency
