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.
