Description
The Mishimoto MMCP-4SBK is a 4-inch black silicone straight coupler engineered from 100-percent silicone for use in custom air intake systems, piping, and cooling circuits. Built with heat-resistant embedded fibers, this straight-shaped coupler is designed to handle demanding underhood conditions where flexible, durable connections matter.
Whether you’re fabricating a custom cold air intake, joining sections of an air intake system, or connecting cooling components, this Mishimoto silicone coupler offers a reliable link point that tolerates high heat and pressure. Its 100-percent silicone construction resists the cracking and hardening that can affect lesser rubber couplers over time, while its coolant-compatible design makes it suitable for cooling system applications as well as intake builds. The straight shape and 4.2-inch outside diameter make it a practical choice for fabricators and enthusiasts assembling or upgrading an air intake filter housing, cold air intake piping, or coolant hose routing where a dependable silicone straight coupler is needed.
Vehicle Applications
The Mishimoto MMCP-4SBK straight coupler is a universal-application component rather than a vehicle-specific part; no specific make, model, or engine fitment is listed for this coupler. It is intended for use by builders and installers connecting piping in custom air intake systems or cooling circuits where a 4-inch silicone straight coupler is required.
