Description
The Mishimoto MMCP-225SBK is a 2.25-inch black silicone straight coupler engineered from 100-percent silicone with embedded heat-resistant fibers, giving it high heat and pressure tolerances for demanding piping connections. This straight-shaped coupler measures 2.25 inches at its inside diameter and 2.45 inches at its outside diameter, making it a durable link for custom air intake and piping builds.
Whether you’re piecing together a custom cold air intake system, replacing a worn coupler in an existing air intake filter housing, or extending intake piping runs, this silicone coupler delivers a flexible yet rugged connection point. Built entirely from silicone rather than ordinary rubber, it’s designed to handle the heat and pressure swings common in engine bay plumbing, and Mishimoto backs the piece with its Lifetime Warranty. Because it’s also coolant compatible, this 2.25-inch straight coupler can serve double duty on cold air intakes, cooling circuits, or any application where a black silicone air intake filter connector or piping coupler is needed.
Vehicle Applications
The MMCP-225SBK is a universal-fit component rather than a vehicle-specific part — Mishimoto does not list specific make, model, chassis, or engine applications for this coupler. That makes it a versatile choice for custom cold air intake builds, intake piping repairs, and general silicone plumbing upgrades across a wide range of vehicles and projects, anywhere a 2.25-inch straight silicone coupler is called for.
