Koyo Performance Radiator - Mazda3 (BK) / Ford Focus XR5 Turbo (LV) - MT
Koyorad builds all aluminium radiators to the same exacting standard used across its motorsport and OEM supply lines, and this unit is a direct replacement for the Mazda3 BK and Ford Focus XR5 Turbo. Nocolok furnace brazed and hand welded with a billet filler neck, it's engineered to shift more heat than the factory unit while bolting straight into the stock location. SKU KH061816.
This listing covers the Mazda3 BK (MPS turbo and SP23 naturally aspirated, hatch and sedan) and the Ford Focus XR5 Turbo (LV), both manual transmission only. Cross referenced part numbers include KH061816, KS061816, and KHXR5ST.
Important: this radiator is manual transmission (MT) applications only — it is not compatible with automatic variants.
