Koyo HH Series Aluminum Radiator

The Koyo HH080300 is a high-performance radiator from the Koyo Racing HH Series, engineered to significantly enhance cooling for specific Honda models. Designed for 1992-2000 Honda Civics and 1993-1997 Honda Del Sols equipped with 1.6L, 1.8L, or 1.5L DOHC engines and a manual transmission, this radiator offers a substantial upgrade over stock. Featuring a "Hyper Core" with high-density fins, this radiator provides 20% to 30% more cooling capacity than OEM units, making it ideal for high-revving, performance-oriented engines and vehicles subjected to extreme heat or operating in demanding conditions. The radiator is constructed entirely from aluminum, with hand-crafted heliarc welds for superior durability and strength along the aluminum connections. Its "custom-built OEM fit" design ensures direct compatibility with factory fans and hoses, eliminating the need for universal fit parts and guaranteeing precise installation. Koyo builds these radiators in their ISO 9001 certified factory and individually triple pressure tests each unit for quality assurance. The radiator boasts a signature brushed aluminum finish and a robust 48mm core thickness, contributing to its enhanced thermal performance. It's important to note that this radiator is not compatible with the OEM radiator cap; a deep plunger style cap, such as the Koyo SK-C13, is required. This product is subject to California's Proposition 65 warning regarding potential cancer and reproductive harm.
