Koyo Performance Radiator N-FLO Dual Pass - Mazda RX-7 (FC) 1986-1991
Koyorad builds all aluminium racing radiators to a genuine motorsport standard, and this N-FLO Dual Pass unit is purpose engineered for the Mazda RX-7. The rotary's tight engine bay and heat output push factory cooling to its limits, so Koyorad uses precision welded internal partitions to double the coolant's dwell time in the core, pulling more heat out before it returns to the 13B.
This listing covers the Mazda RX-7 FC3C Convertible and FC3S Coupe, including both the naturally aspirated 13B and 13B-DEI Turbo variants, from 1986 to 1991. It's a direct bolt-in replacement, retaining OEM fan shroud mounts and stock hose fitment with no cutting or modification required.
