Description
The Mishimoto MMCP-25275BK is a black silicone transition coupler engineered to bridge a 2.5in opening to a 2.75in opening, giving it a straight transition shape that’s purpose-built for air intake system plumbing. Built from 100-percent silicone with heat-resistant embedded fibers, this coupler is designed to handle the demands of intake piping where two different tube diameters need to be joined securely.
Whether you’re upgrading an existing air intake system or fabricating a custom cold air intake setup, a properly sized transition coupler like this one is what allows mismatched pipe or filter-side diameters to mate cleanly and seal well. Mishimoto’s silicone construction and embedded fiber reinforcement give this coupler high heat and pressure tolerances, and it’s also coolant compatible, making it a flexible choice for intake and coolant plumbing projects that call for a 2.5in-to-2.75in straight transition piece. As a universal component, it pairs easily with intake pipe, filter necks, and other air intake filter hardware where diameter mismatches occur.
Vehicle Applications
This Mishimoto transition coupler is offered as a universal-fit component rather than a vehicle-specific part, making it suited to any air intake system build or repair that requires stepping between a 2.5in and a 2.75in connection point. Because it isn’t tied to a particular make or model, it works as a general-purpose piece for custom cold air intake and intake piping projects wherever this diameter combination is needed.
