Koyo 53mm Performance Radiators


JDM Obsession is proud to be an authorised distributor for Koyo K-Sport Aluminium Radiators.

Koyo is Japan's largest aftermarket radiator manufacturer. Koyo is a Japanese company established in July of 1956 as Ejiri Radiator in Nagoya, Japan as a radiator repair shop. Fast forward 55 years later and Koyo products are renowned around the world for quality, fitment, and performance.

Why buy a Koyo radiator?

Precise Tube and Fin Alignment

Construction under strict quality control and solid boxing result in tubes with optimal coolant flow and fins with highly efficient heat transfer.

Nocolok Brazing

Tubes, Fins, Headers and Brackets are brazed in a state-of-the-art Nocolok furnace, bonding all components to resist damage from vibration, road debris, and the elements.

Billet Filler Neck

Precision machined billet filler necks are incorporated on each Koyo radiator for strength, durability and better sealing.

OE Specific Mounting and Hand Crafted Heliarc Welds

Koyo incorporates application specific mounting locations for all fan shrouds, inlet/outlet hoses and top/bottom mounting pins, ensuring quick and pain-free installs. Each Koyo All Aluminum Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminum to aluminum bond, to mate all components
