Mishimoto 1.3 Bar Radiator Cap

The Mishimoto 1.3 Bar Radiator Cap is a high-pressure replacement radiator cap. It raises the cooling system's operating pressure to 1.3 bar (about 18.8 PSI). Higher system pressure raises the coolant's boiling point. This helps the engine resist boil-over and hot spots during spirited driving, towing, track days, and hot weather.

Key Features:

• 1.3 bar (approximately 18.8 PSI) pressure rating for a higher coolant boiling point
• Replaces a worn or lower-rated radiator cap
• Durable, corrosion-resistant construction for long service life
• Pressure-relief spring and sealing gasket for a reliable seal on the radiator filler neck
• Available in different cap styles to suit different radiator filler necks

A radiator cap that holds pressure properly is a simple, inexpensive way to support cooling performance. It suits both daily drivers and modified vehicles. Choose the variant that matches your radiator's filler neck.
