Description
The Mishimoto MMCP-20225BK is a purpose-built 2.0in to 2.25in silicone transition coupler engineered for builders piecing together a custom cold air intake, turbo plumbing, or coolant routing setup. Molded in black, this straight transition coupler bridges two different hose diameters into one clean, leak-resistant connection point without the guesswork of adapting mismatched tubing.
Whether you’re fabricating a custom air intake system, tying together an intake filter housing, or completing coolant lines that need a reliable step-down fitting, this coupler gives you a dependable silicone connector built from 100-percent silicone with heat-resistant embedded fibers for high heat and pressure tolerances. Mishimoto backs this transition coupler with its Lifetime Warranty, making it a practical building block for anyone assembling or upgrading an air intake, cool air intake, or coolant system where standard cold air intake filter hoses and factory tubing just won’t match up.
Vehicle Applications
This is a universal-fit silicone transition coupler rather than a vehicle-specific part, designed to step between 2.0in and 2.25in diameter hose or piping wherever that size transition is needed. It suits custom intake fabrication, turbo piping, and coolant plumbing projects across a wide range of builds, giving fabricators and DIY installers a flexible connector for air intake systems, intake filter housings, or coolant lines that require this specific diameter change.
