Billet Radiator Cap - 18-psi Black

The DRAG RACE SOLUTIONS Billet Radiator Cap – 18-psi Black is a precision-engineered component designed for high-performance and modified vehicles where factory caps may not suffice. This cap is ideal for automotive enthusiasts and mechanics who require reliability under extreme conditions, particularly in applications involving aggressive tuning, nitrous oxide systems, or supercharger installations.

Constructed from solid billet aluminum, this cap features a black anodized finish that resists corrosion and enhances durability. The 18-psi pressure rating elevates the coolant boiling point, which is crucial for modified engines that operate at higher temperatures. The precision-machined sealing surfaces ensure a leak-free connection to your radiator, providing superior heat dissipation compared to standard plastic caps.

This radiator cap is particularly beneficial for drag racers, turbo and supercharger conversions, and any vehicle running elevated coolant pressures beyond factory specifications. Installation is straightforward—simply remove your existing cap and thread this unit onto your standard radiator neck for enhanced performance and reliability.
