Direct-fit, tool-free replacement - no tuning or modification needed
Eliminates seized caps, coolant leaks and spring failure under heat
Also fits Focus ST Mk3 and Mk4 - same spec, same fitment
Track-proven reliability, not just shiny metal. For fast-road drivers and track-day regulars who value function over fluff.
