PRODUCT DESCRIPTION
To get the most out of your high-performance parts, details are key. Under demanding driving conditions, your vehicle's cooling system is put under high pressure. Stock radiator caps are not designed to withstand high pressure, resulting in fluid leaks into the overflow tank. The Mishimoto 1.3 Bar High-Pressure Radiator Cap is designed to withstand higher pressure, keeping coolant where it belongs—flowing within the system. Pressure rated to 1.3 bar (19 pounds). Fits most domestic vehicles. Raises engine coolant boiling point to provide a safer, more efficient cooling system. Ergonomic design for easy removal and installation. Installing a new cap can prevent overheating and cooling system failure. Pressure tolerance: 1.3 bar / Compatible with 42mm filler necks. Mishimoto Lifetime Warranty.
