Description
The Mishimoto MMCP-3035BK is a purpose-built silicone transition coupler engineered to step piping from 3 inches down to 3.5 inches, giving builders a reliable way to join mismatched diameters in an air intake system. Molded in black from 100-percent silicone with heat-resistant embedded fibers, this coupler is designed to handle the demands of a custom cold air intake or piping setup without sacrificing durability.
Whether you’re fabricating a custom cold air intake, upgrading an existing air intake filter housing, or simply need a dependable transition piece to connect intake tubing of different sizes, this Mishimoto coupler is built to bridge that gap. Its straight transition shape and coolant-compatible silicone construction make it a versatile choice for enthusiasts assembling their own air intake systems who need a durable link between components rather than a pre-molded, vehicle-specific bend. Mishimoto backs the coupler with high heat and pressure tolerances baked into its silicone formulation, making it a practical building block for anyone piecing together a cold air intake or intake filter setup from the ground up.
Vehicle Applications
This transition coupler is offered as a universal fitment component rather than being tied to a specific make, model, or engine per Mishimoto’s published application data. That makes the MMCP-3035BK a flexible option for custom air intake builds, piping repairs, or fabrication projects where a 3-inch to 3.5-inch silicone transition is needed, regardless of the vehicle it’s installed on.
