Description
The Mishimoto High-Pressure Radiator Cap (1.3 bar) is a smart cooling upgrade for many vehicles with standard 31-32mm fill necks. It replaces factory caps not built for higher pressure or extreme driving, raising system pressure to 1.3 bar (19 psi) and increasing the coolant boiling point for safer operation. Built from high-strength alloy steel with an ergonomic screw-in design, it resists corrosion and stays sealed even after repeated removal, delivering an OEM-level fit with no modifications required.
