Description
The Mishimoto MMCP-2530BL is a purpose-built 2.5-inch to 3-inch silicone transition coupler, finished in blue and engineered to join differing diameter sections of tubing within an air intake system. Built entirely from silicone with heat-resistant embedded fibers, this coupler is designed to handle the demands of piping transitions where size mismatches occur.
Whether you’re piecing together a cold air intake, reworking intake piping on a custom air intake system, or simply need a reliable step-up coupler between a 2.5-inch and 3-inch section, the Mishimoto MMCP-2530BL bridges the gap. Its 100-percent silicone construction and heat-resistant embedded fibers give it high heat and pressure tolerances, and Mishimoto backs it with high heat and pressure tolerances plus a Mishimoto Lifetime Warranty. Because it’s coolant compatible, it can also be used in coolant-side plumbing where a straight, size-transitioning connector is needed, not just on the intake filter side of the system.
Vehicle Applications
This is a universal straight transition coupler rather than a vehicle-specific fitment part — Mishimoto does not list specific make, model, chassis, or engine code applications for the MMCP-2530BL. It’s intended to connect any 2.5-inch and 3-inch diameter piping sections, making it a flexible option for custom cold air intake builds, piping repairs, or fabrication projects where an air intake filter, intake tubing, or coolant line needs a size transition. Mishimoto notes that this hose pairs well with its own universal piping and hose clamps, including options such as MMCLAMP-275, MMCLAMP-325, MMCLAMP-WG-76HT, MMCLAMP-WG-95HT, MMCLAMP-CTWG-92, and MMCLAMP-CTWG-105, along with universal aluminum and stainless piping options like the MMICP-AL and MMICP-SS series.
