PRL Motorsports Titanium High-Performance Radiator Cap – Type A | 1.3 Bar

Overview

Your cooling system’s pressure cap is a frontline defense against boiling, vapor lock, and overflow. Our titanium version retains the same 1.3 bar (≈18.8 psi) pressure rating that reliably raises the coolant’s boiling point, while adding the advantages of titanium.

Why Titanium?

Titanium offers unmatched durability, corrosion resistance, and temperature stability, even in harsh environments. The radiator cap's naturally high tensile strength ensures years of consistent sealing and performance, while the titanium burnt ombre finish adds a custom aesthetic that evolves over time with heat exposure.

The burnt ombre surface produces blue, bronze, and gold tones that shift under changing light and temperature. The laser-etched PRL logo keeps branding subtle and refined. Inside, we maintain the same robust spring and silicone gasket used in our standard caps, ensuring dependable sealing and consistent performance across repeated cycles.

It’s built for daily drivers, high-performance street builds, and track machines where reliability is non-negotiable, especially in extreme thermal environments.
