PRODUCT DESCRIPTION
Mishimoto has developed a Carbon Fiber Radiator Cap to enhance under-hood styling while still maintaining pressure in the cooling system. For maximum performance from your parts, details are key. Under demanding driving conditions, your vehicle's cooling system becomes significantly pressurized. Stock caps are not designed to withstand higher pressures, leading to fluid leaking into the overflow reservoir. The Mishimoto radiator cap is engineered to withstand higher pressure, keeping coolant where it belongs, flowing through your system. Its sleek carbon fiber exterior will give an unexpected touch of style. Constructed from hand-laid carbon fiber. 1.3 bar (19 PSI) pressure rating. Fits most import 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 31–32mm filler necks / Note: Not compatible with stock KTM radiators. Mishimoto Lifetime Warranty.
