Description
Mishimoto’s 45-Degree Silicone Transition Coupler (MMCP-R45-25275RD) is a purpose-built length of red silicone tubing that steps intake piping down from 2.75 inches to 2.50 inches while bending the airflow path 45 degrees. It’s the kind of connector piece that turns a straight run of pipe into a properly routed cold air intake system, matching mismatched tube diameters without forcing an awkward straight-line fit.
Because so many cold air intake and air intake filter setups mix and match piping from different sources, a reducer coupler like this one is often the missing link between a filter housing, a sensor tube, or a factory air box outlet. Whether you’re finishing off a custom cold air intake, adapting an air intake system, or simply need a 45-degree transition to keep your intake filter and tubing aligned correctly, this Mishimoto coupler is molded from silicone to handle the flexing and heat cycling that intake plumbing sees under the hood. It’s a straightforward way to complete cold air intakes projects where a factory-style rubber elbow isn’t available in the size or angle you need.
Vehicle Applications
This coupler is not listed for a specific make or model; it’s a universal-fit transition piece sized to work anywhere a 2.50-inch to 2.75-inch, 45-degree connection is needed in an intake tract. That makes it a practical option for custom air intake builds, intake filter relocations, or repairs on cold air intake systems where two different pipe diameters need to be joined at an angle rather than in a straight line.
