GrimmSpeed - Titanium Radiator Cap – 1.3 Bar - GRM.1013.1.TI

Underneath the new finish, the engineering remains the same; a 1.3 bar (18.9 psi) pressure rating designed to raise the boiling point of your coolant, maintain system pressure, and keep fluid sealed even during extreme heat cycles. Whether you’re running an antifreeze mix or distilled water for track use, consistent pressure means better thermal stability and fewer chances for overflow. The GrimmSpeed Titanium Radiator Cap is more than just a beautiful accent for your engine bay; it’s a precision part built to perform. Pressure Rating: 1.3 bar / 18.9 psi Finish: Burnt ombre titanium (blue-to-bronze gradient) Seal: Heavy-duty silicone gasket for consistent sealing Construction: Reinforced spring assembly for repeatable pressure retention Fits all Subaru radiators and/or expansion tanks using the standard small-type cap interface Also compatible with many Nissan, Mitsubishi, Honda, Mazda, and Toyota applications sharing the same small-type neck design Installs just like the OEM cap — no modifications required Confirm that your radiator or expansion tank uses the small-type neck before installation
