The Mishimoto full-flow thermal bypass valve kit for 2017+ Ford Raptor 3.5L EcoBoost replaces the factory bypass to allow continuous fluid flow through the external cooler. Its all-aluminum CNC housing and full-flow design improve cooling under towing, hot climates, and extreme driving, eliminating the stock valve's failure point. The kit installs quickly in about an hour.
