A higher-rated radiator cap raises the coolant system's boiling point, giving you a bit more margin before you're pushing into steam and pressure relief territory on a hot track day or a long pull in traffic. It's a cheap, low-effort upgrade that pairs well with any cooling system work you're already doing.

Features

• Increased pressure rating over the factory cap
• Raises the coolant system's effective boiling point
• Direct fitment, no adapters required
• Affordable complement to broader cooling upgrades
