Description
The Mishimoto MMCP-22525BK is a straight silicone transition coupler built to step down or step up piping from 2.25 inches to 2.5 inches inside diameter, making it a go-to piece for custom air intake system fabrication, turbo piping, and coolant hose runs. Molded from 100-percent silicone rather than rubber, this coupler is designed to hold its shape and seal reliably at the junction of two different-sized tubes.
Whether you’re piecing together a custom cold air intake, replacing a cracked factory coupler, or building out intercooler and coolant plumbing, having the right transition coupler on hand keeps the whole air intake system sealed and leak-free. This Mishimoto coupler uses heat-resistant embedded fibers for reinforcement and is engineered for high heat and pressure tolerances, so it can handle the demands of an under-hood environment better than a basic off-the-shelf rubber hose. It’s also coolant compatible, extending its usefulness beyond intake piping into cooling system applications. Because it comes in black, blue, red, green, purple, and white, it’s easy to color-match an intake filter setup or engine bay theme while still getting a functional, properly sized transition piece.
Vehicle Applications
This is a universal-fit silicone coupler rather than a vehicle-specific part, so it isn’t tied to a particular make, model, or year. Instead, it’s sized to fit any application requiring a straight transition from 2.25-inch to 2.5-inch diameter tubing, which makes it a practical addition to custom air intake, turbo, or coolant hose builds where off-the-shelf couplers don’t match your piping.
