Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicles cooling system becomes highly pressurized. OEM caps are not equipped to handle higher pressure, causing fluid to leak out into the overflow reservoir. The Mishimoto radiator cap is rated at a higher pressure and will keep coolant where it needs to be-flowing within the system.Rated at 1.3 Bar (19lbs) pressure. Fits most domestic vehicles.
I wanted to love this radiator cap because the specs seemed great, but it arrived with a dent. Ended up having to return it. I hope the replacement works better because I’ve heard good things about Mishimoto.

Great Upgrade for My Honda
I swapped out my old radiator cap for the Mishimoto high pressure 1.3 bar cap and I can already see a difference! It holds pressure better and seems to keep my engine cooler. Definitely worth it for anyone looking to boost their cooling system.

A Bit Stiff at First
The Mishimoto cap is nice and all, but it was really stiff when I first tried to attach it. After a few tries, it finally clicked into place. Once on, it does its job well, so I’m satisfied for the most part.
