Description
The Mishimoto MMCP-25SBK is a 2.5-inch straight silicone coupler built to link sections of your air intake system with a durable, heat-resistant seal. Molded from 100-percent silicone and reinforced with embedded fibers, this coupler is engineered to handle high heat and pressure, and it’s finished in black for a clean, factory-style look under the hood. It’s part of Mishimoto’s lineup of couplers, which are available in six colors so you can match your existing intake setup or build.
Whether you’re piecing together a custom cold air intake, repairing a worn section of your factory air intake system, or upgrading intake piping alongside a cold air intake filter, a quality silicone coupler is the connection point that keeps everything sealed under load. This MMCP-25SBK straight coupler is rated to a maximum temperature of 330°F and is coolant compatible, making it a versatile choice for joining 2.5-inch intake piping. Because it’s silicone rather than rubber, it resists the heat cycling and pressure demands that intake and coolant plumbing can see, helping maintain a tight, reliable seal at the connection.
Vehicle Applications
The MMCP-25SBK is a universal-fit silicone coupler rather than a vehicle-specific part, so it isn’t tied to a particular make, model, or year. Instead, it’s designed to connect any 2.5-inch intake piping run, making it a practical fit for custom air intake builds, intake system repairs, or upgrades where 2.5-inch diameter piping is used. Mishimoto notes that this hose pairs well with its own clamps (MMCLAMP-275, MMCLAMP-WG-76HT, MMCLAMP-CTWG-92) and universal aluminum intake piping (MMICP-AL-2750, MMICP-AL-2759, MMICP-AL-2751, MMICP-AL-30, MMICP-AL-39, MMICP-AL-31, MMICP-AL-40) for a complete, properly sized connection.
