Skunk2 Type A High Pressure Radiator Cap 1.3 kg/cm for Select 1988-2001 Honda Acura Mazda Mitsubishi Subaru

Fits select 1988-2001 Honda Civic, CRX, Prelude, and Acura Integra (1.5L / 1.6L / 1.8L / 2.2L / 2.3L).

Skunk2 High-Pressure Radiator Caps are engineered to optimize cooling system efficiency by increasing internal system pressure. This Type A cap features an open valve pressure of 1.3 kg/cm², which is approximately 0.2 kg/cm² higher than most factory OEM radiator caps. By increasing this pressure, the coolant boiling point is raised, providing a critical safety margin and more efficient heat dissipation under the high-load conditions of competitive racing or spirited street driving.

Designed as a functional engine bay upgrade, this cap is fully compatible with Skunk2 silicone radiator hoses and most high-performance aftermarket radiators. It replaces worn factory caps to ensure your cooling system maintains the pressure required for peak engine performance.
