Description
The Mishimoto MMCP-25SGN is a 2.5-inch straight silicone coupler built for air intake systems and piping that demand a tight, reliable seal. Molded from 100-percent silicone with heat-resistant embedded fibers, this green-finished coupler is designed to join intake tubing sections with a durable, flexible connection point. It’s available in six colors, letting builders match the coupler to their engine bay while keeping the same straight-shape design and performance.
Whether you’re assembling a custom cold air intake, upgrading an existing air intake system, or refreshing the piping around your intake filter, a quality silicone coupler is what keeps the connection between sections airtight and leak-free. The MMCP-25SGN’s embedded fiber reinforcement gives it high heat and pressure tolerances, helping it hold up to the demands of a cool air intake setup better than a basic rubber coupler. Because it’s coolant compatible, this straight coupler can also be used in cooling system plumbing wherever a 2.5-inch connection is needed, extending its usefulness beyond just the air intake filter side of the build. For a complete piping job, Mishimoto notes this coupler pairs with its own hose clamps and universal aluminum piping options.
Vehicle Applications
The Mishimoto MMCP-25SGN is offered as a universal-fit coupler rather than a vehicle-specific part—Mishimoto does not tie this straight silicone coupler to a particular make, model, chassis, or engine code. That makes it a practical choice for custom air intake systems, intercooler and cooling piping runs, and general fabrication projects where a 2.5-inch straight silicone connection is needed, rather than being limited to one specific vehicle application.
