Titanium Radiator Cap – 1.3 Bar for Subaru Radiators & Expansion Tanks by GrimmSpeed
A small detail that makes a big impact. The GrimmSpeed Titanium Radiator Cap takes everything that made our standard 1.3 bar cap a trusted cooling upgrade and gives it a whole new look, feel, and finish worthy of the most refined Subaru builds.
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.
Please Note: Does not replace the earless, 1-way STI radiator cap — fits the upper expansion tank on those models
