The Koyorad Aluminum Racing Radiator model VH012663 is designed for a range of vehicles including the Scion FR-S (2013-2016), Subaru BRZ (2013-2021), and Toyota 86 (2017-2021). This radiator is part of the Hyper V-Core series, which is Koyorad's latest line of high-performance all-aluminum radiators.Key Features and Specifications:All-Aluminum Construction: The Koyorad VH012663 radiator features all-aluminum construction, providing improved cooling efficiency and increased durability compared to factory radiators that often have plastic components. The all-aluminum build is resistant to the expansion and cracking that can occur in plastic tanks due to constant heat cycles??????.Hyper V-Core Technology: The radiator includes a high-density fully brazed Hyper-V Series 1.4" cross-flow core. This design helps in significantly increasing the surface area for heat transfer while still allowing for optimal air circulation through the radiator. This technology is particularly useful for vehicles that experience extreme heat and have limited space, where maintaining efficient cooling is crucial????.Compatibility: This model fits both manual and automatic transmissions, although it's often listed specifically for manual transmissions. It retains mounts for the stock fan shrouds and fans, and is designed to accept OEM radiator hoses and AC condenser, which means no modifications are required for installation??????.Enhanced Durability: The radiator features heli-arc welded connections, a thicker core, and precise tube and fin alignment for durability and performance. It also boasts NoClock Brazing on the tubes, fins, headers, and brackets, providing resistance to damage from vibration, road debris, and the elements??.Efficient Heat Transfer: The fin and tube pitch are designed to promote optimal coolant flow, ensuring efficient heat transfer and helping to keep engine temperatures down during high-demand situations??.Quality Assurance: Koyorad's production facilities are privately owned, allowing them to oversee each stage of radiator production. The radiators are hand assembled, Nocolok? brazed, then TIG welded by hand with premium aluminum. They are also triple pressure tested during the manufacturing process to ensure reliability and performance?
