Mishimoto 1.3 Bar Rated Radiator Cap Large Domestic

This Mishimoto radiator cap is rated at 1.3 Bar (19 psi), which is higher than many stock caps. When your engine works hard, especially during spirited driving or in hot weather, the cooling system builds up pressure. Standard caps might let pressurized coolant escape into the overflow tank, reducing the amount of coolant in the radiator and potentially leading to overheating. This higher-rated cap helps keep that coolant contained within the system, raising the boiling point of your engine coolant. This means your cooling system can operate more efficiently and safely, even under demanding conditions.

Designed with an ergonomic grip, removing and installing this cap is straightforward. It’s a simple yet effective way to ensure your cooling system is working at its best, especially if you’ve added other performance cooling components or frequently push your vehicle.
