Moroso Racing Radiator Cap - 19-21lbs

This is a Moroso racing radiator cap, rated for 19 to 21 pounds of pressure. A radiator cap does more than just seal your cooling system; it's a crucial component that helps maintain the correct operating temperature by allowing the coolant to boil at a higher temperature under pressure. This particular cap is designed for applications where a higher pressure rating is needed to keep engine temperatures in check, especially during demanding use.

Moroso builds this cap with durable materials to withstand the heat and pressure cycles found in performance or racing engines. The higher pressure rating means your coolant can reach a higher temperature before boiling, which is beneficial for preventing overheating in high-performance situations. It's a straightforward replacement for your stock cap, but it's important to ensure your cooling system is designed to handle the increased pressure.
