Description
The Mishimoto MMCP-22525BL is a blue, 100-percent silicone transition coupler engineered to bridge 2.25-inch and 2.5-inch diameter piping, giving builders a reliable connection point when stepping between different tube sizes in a custom air intake system. Built with heat-resistant embedded fibers, this coupler is designed to handle the demands of engine bay temperatures and pressure while remaining coolant compatible for broader plumbing use.
Whether you’re finishing off a custom cold air intake, tying together universal aluminum piping, or completing a cool air intake plumbing project, this silicone coupler gives you a flexible, durable transition piece rather than a rigid, one-size-fits-all part. Its straight transition shape and 100-percent silicone construction make it a dependable choice for anyone piecing together an air intake system, and because it’s coolant compatible, it can also serve coolant routing needs where a 2.25in-to-2.5in silicone connector is required. As a universal component, it pairs well with aftermarket air intake filter setups and intake piping from a variety of builds, letting you fine-tune diameter transitions without hunting for a fixed-fitment hose.
Vehicle Applications
This Mishimoto coupler is offered as a universal-fit silicone transition piece rather than a vehicle-specific part, so no particular make, model, or engine application is specified by the manufacturer. It’s intended for use in custom or universal air intake and piping setups where a 2.25-inch to 2.5-inch silicone connection is needed, making it a flexible option for a range of intake and plumbing projects rather than a single fitment.
