Description
The Mishimoto MMCP-25SBL is a 2.5-inch straight silicone coupler built specifically for air intake system plumbing, offered here in Blue as part of a six-color lineup. Molded from 100-percent silicone with heat-resistant embedded fibers, this coupler is engineered to handle high heat and pressure while linking sections of 2.5-inch intake tubing together.
Whether you’re fabricating a custom cold air intake, repairing an existing air intake system, or building out turbo piping, a quality silicone coupler like this one is the connective piece that keeps everything sealed and secure. Unlike a rigid air intake filter or intake filter housing, this coupler is a flexible transition piece designed to join pipe ends of matching diameter, and its silicone construction with embedded fiber reinforcement helps it stand up to the heat and pressure found in engine bay air intake routing. Mishimoto backs this coupler with high heat and pressure tolerances up to a 330°F maximum temperature rating, and it’s also coolant compatible, giving builders flexibility beyond just intake ducting.
Vehicle Applications
Manufacturer data does not tie the MMCP-25SBL to a specific make, model, or engine code, so this is a universal 2.5-inch straight coupler rather than a vehicle-specific part. It’s intended to fit any air intake system, cold air intake build, or custom piping setup that uses matching 2.5-inch diameter tubing, making it a versatile connector for DIY intake fabrication and repair work across a wide range of applications where 2.5-inch pipe is used.
