Raising system pressure raises coolant's boiling point, giving the cooling system more headroom before it starts to struggle — a small, simple upgrade that genuinely helps in hot climates, on daily drivers, or under spirited driving. PRL's cap is built from high-quality materials to hold up to sustained heat and pressure, with a clean, performance-oriented design that dresses up the engine bay in the process.
