Description
The Mishimoto MMCP-275SBK is a 2.75-inch black silicone straight coupler engineered to join sections of tubing in custom air intake systems and piping setups. Molded from 100-percent silicone with heat-resistant embedded fibers, this coupler is built to handle demanding underhood conditions where ordinary rubber hose falls short.
Whether you’re piecing together a cold air intake, upgrading an existing air intake filter housing, or fabricating a custom piping run, a dependable coupler is the connection point that keeps everything sealed and secure. The MMCP-275SBK’s straight shape and 2.75-inch end diameter make it a practical choice for linking tubing sections in an air intake system, and its high heat and pressure tolerances mean it can stand up to the environment found near an engine bay far better than generic couplers. Mishimoto backs this coupler with its Lifetime Warranty, giving builders confidence when integrating it into a cold air intake or custom intake filter setup.
Vehicle Applications
The MMCP-275SBK is a universal-fit silicone coupler and is not tied to a specific make, model, or year. It’s designed to work with any application using compatible 2.75-inch tubing, making it a flexible component for custom cold air intake builds, piping repairs, or fabrication projects rather than a fitment-specific part.
