Skunk2?s all-aluminum, half-size Alpha Series Radiator for the 88-?91 Civic/CRX is a direct-fit upgrade designed to dramatically increase both cooling efficiency and engine performance. Alpha Series Radiators are manufactured from lightweight and durable aluminum, feature 100-percent brazed cores, and include polished end tanks with Skunk2?s signature Alpha logo embossed along each side. Each Alpha Series Radiator features a dual-core design, high-efficiency fins for maximum cooling capabilities, and includes a genuine Skunk2 Radiator Cap for maximum performance and a premium appearance. Each Alpha Series Radiator also includes provisions for the OEM cooling fan and larger 1.25-inch inlets and outlets, which makes it ideal for most engine swaps that utilize larger radiator hoses.
