Skunk2’s Fine Tuning products and accessories, like its high-pressure Radiator Caps, help put the finishing touches onto your vehicle you work so hard to make perform well. Skunk2 Radiator Caps increase internal radiator pressure, which results in a higher coolant boiling point and a more efficient cooling system. Skunk2 Radiator Caps feature an open valve pressure of 1.3 kg/cm—that's .2kg/cm higher than most OEM radiator caps. High-pressure radiator caps like Skunk2’s demonstrate their effectiveness under high-load conditions on both race cars and street cars alike. Skunk2’s high-pressure Radiator Cap Type A fits '88-'91 Civics, '90-'93 Integras, '92-'01 Preludes, and most Mazdas, Mitsubishis, Nissans, and Subarus, as well as most aftermarket radiators.
