R SERIES 53mm Core Thickness
Built with a robust 53mm core, the R-Core Series is engineered for the serious performance tuner. Increased capacity means better cooling reserve when you need it. Intended for both circuit and daily use, you may double your coolant capacity and see up to 35% increased performance over your stock radiator. Unless noted otherwise, all Koyorad R-Series All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans. See notes in individual item descriptions for details.
Features:
-
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 Mountin: Koyo incorporates application specific mounting locations for all fan shrouds, inlet/outlet hoses and top/bottom mounting pins, ensuring quick and pain-free installs.

Hand Crafted Heliarc Welds: Each Koyo Alloy Race Radiator is Heliarc welded individually by hand. This creates the strongest aluminum to aluminum bond to mate all components.
