Cobb Radiator Cap

  • Keep your engine cool by upgrading to the Cobb 1.3 bar radiator cap. This higher pressure cap increases the effective boiling temperature of coolant in the system. The higher temperature allows the cooling system to absorb more heat. The cap increases pressure, and does allow temperature to go up about 10 degrees before fluid boils, but does not reduce temperature. Avoiding boiling makes head gasket failure less likely.
