Replacing the radiator cap in your import or domestic ride with Mishimoto high-pressure caps is smart. OEM caps can't handle the higher pressure of your cooling system when faced with hard driving conditions. Rated at 19 lbs. of pressure, these caps are available in sizes and styles to fit your vehicle. Mishimoto offers their standard high-pressure caps, carbon fiber caps to enhance the looks of your engine bay, and temperature gauge caps to view an accurate temperature reading of your coolant! All have the Mishimoto logo. So, keep your coolant where it needs to be--flowing within your system!
