Description
The Mishimoto MMCP-30SBK is a 3-inch black silicone straight coupler built to join tubing sections in air intake systems and other under-hood plumbing runs. Constructed from 100% silicone with heat-resistant embedded fibers, this straight coupler is engineered for high heat and pressure tolerances, making it a durable link between piping components.
A quality silicone coupler is a small but important piece of any air intake system, cold air intake build, or coolant line setup, and the MMCP-30SBK is designed to hold up where flexibility and heat resistance matter most. Whether you’re assembling a custom cold air intake, connecting universal piping, or replacing a worn coupler feeding an air intake filter, this straight, black silicone section is meant to bridge tubing securely while standing up to the heat and pressure found in these systems. It’s also coolant compatible, extending its usefulness beyond intake piping alone.
Vehicle Applications
The MMCP-30SBK is a universal-fit component rather than a vehicle-specific part, so it isn’t limited to a single make or model. This makes it a flexible option for custom air intake, cooling, or piping projects across a wide range of platforms. Mishimoto notes that this coupler pairs well with specific clamps—such as the MMCLAMP-325, MMCLAMP-WG-95HT, and MMCLAMP-CTWG-105—as well as universal piping options including the MMICP-SS-21, MMICP-SS-250, MMICP-SS-259, MMICP-SS-251, MMICP-SS-30, MMICP-SS-39, and MMICP-SS-31, allowing builders to complete a full custom intake or piping system.
