Description: PRL Titanium Radiator Cap (1.3 Bar/18.8 PSI)

Details:

We're introducing the PRL Titanium Radiator Cap, a premium evolution of our trusted 1.3 bar design.

This new variant features a titanium finish that has unmatched corrosion durability. Each cap is finished in a burnt ombre hue that makes every piece one-of-a-kind, and lasered with our unmistakable PRL Motorsports logo.

With a 1.3 bar (≈18.8 psi) pressure rating, this cap raises the coolant boiling point and ensures consistent system pressure under demanding conditions. Inside, you’ll find our proven reinforced spring assembly and high-temp silicone gasket, both tested for long-term sealing and reliability.
