Koyo 86-88 Mazda RX-7 FC NA/Turbo (MT) Radiator – HH060642

The Koyo HH060642 is a performance-grade aluminum radiator designed for early second-generation Mazda RX-7 models. Built specifically for 1986-1988 FC chassis with the 1.3L naturally aspirated or turbo rotary engine and manual transmission, this radiator offers a direct-fit upgrade that improves cooling efficiency and durability over the factory unit.

With a 48mm high-capacity all-aluminum core and high fin density, the HH060642 delivers superior heat dissipation to keep coolant temperatures stable during spirited street driving, drift events, or extended track sessions. Precision TIG-welded end tanks and Nocolok-brazed construction ensure maximum strength and long-lasting reliability.
