The Koyo HH083833 is an all-aluminum radiator engineered to enhance the cooling performance of your 2022-2025 Honda Civic 1.5L Turbo and 2023-2025 Acura Integra. Built by Koyo Radiator, this upgrade features a high-density Hyper Core, making it nearly twice as thick as the OEM radiator and delivering superior cooling efficiency. Installation is designed to be a 100% direct plug-and-play process, utilizing OEM fans and hoses without requiring any engine modifications. The radiator is constructed with all-aluminum, hand-welded, and furnace-brazed components. Each unit undergoes triple pressure testing during manufacturing in Koyorad's ISO 9001 certified factory, ensuring reliability and durability. The radiator also features a signature Koyorad brushed aluminum finish. A special note regarding installation: this radiator is not compatible with the original OEM radiator cap.
