Skunk2 Alpha Series 06-11 Honda Civic SI Radiator (Dual Core)

Skunk2’s all-aluminum, full-size Alpha Series Radiator for the ’06-’11 Civic Si 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. Each Alpha Series Radiator also includes provisions for the OEM cooling fan and OEM-compatible, 1.25-inch inlets and outlets. Skunk2’s commitment to producing high-quality components means that each Alpha Series Radiator meets or exceeds original equipment manufacturer standards, that each radiator may be installed without modification to the vehicle, and is compatible with OEM hoses, cooling fans, and shrouds. (Note: Some engine swap applications may require custom radiator hoses and/or cooling fans.) Skunk2’s Alpha Series Radiators are the perfect addition to any high-performance vehicle and are designed for the street, the track, or even OEM replacement purposes. Alpha Series Radiators are built to withstand harsh elements as well as against years of under-hood heat cycling. Each Alpha Series Radiator adheres to strict quality control standards and careful packaging, resulting in tubes and fins capable of optimal flow and efficient heat transfer.

Cooling products are essential components to keeping your vehicle running at optimal temperatures. Whether you are looking for a radiator, fans, or oil coolers, we've got you coered with the top brands like Mishimoto, Koyorad, Skunk2, Moroso, and more!

Radiators cool down and store the coolant in your vehicle. Aftermarket radiators typically provide better cooling than factory, and also can really clean up the look of your engine bay. Without proper cooling, your engine can overheat. We recommend upgrading your OEM radiator to and aftermarket radiator if you plan on doing any hard driving for long periods of time, or plan to take your car onto the track for heavy use.
