Description
The Mishimoto MMCP-25275BL is a purpose-built silicone transition coupler engineered to step down from a 2.75-inch diameter to a 2.5-inch diameter, giving fabricators and DIY installers a clean way to bridge mismatched piping in an air intake system. Finished in blue and molded from 100-percent silicone, this straight transition coupler is designed to handle the demands of piping runs where two different tube sizes need to be joined securely.
Whether you’re building out a custom air intake system, repairing an aging air intake filter housing connection, or simply need a dependable coupler for a cold air intake project, this Mishimoto transition piece is designed to provide a tight, flexible seal between two differently sized pipe ends. Its heat-resistant embedded fibers and high heat and pressure tolerances make it a practical choice for intake and piping applications where ordinary rubber couplers can degrade over time. Shoppers researching cold air intakes, cold air inductions, or a cool air intake filter upgrade — including those searching for a cold air intake in Las Vegas or anywhere else — often need a reliable transition point like this to complete their intake filter plumbing correctly.
Vehicle Applications
This coupler is a universal transition part intended for custom and replacement air intake system piping rather than a single factory-specific application. It is built to connect a 2.5-inch diameter section to a 2.75-inch diameter section, making it suited to intake, piping, or hose runs on any setup where that specific size transition is required, regardless of vehicle make or model.
