Description
The Mishimoto MMCP-R90-30375BK is a 90-degree black silicone transition coupler purpose-built to solve the toughest routing challenges in coolant lines and air intake system piping. With one end sized for a 3.2-inch outside diameter and the other for a 3.95-inch outside diameter (3.75-inch inside diameter), this transition elbow bridges mismatched hose sizes while making a clean, tight 90-degree bend that rigid piping simply can’t achieve.
Whether you’re plumbing a custom intercooler pipe, rerouting a coolant hose, or fabricating a fresh air intake, this coupler gives you the flexibility to get around tight engine bay obstructions without kinking or restricting flow. It’s built from four layers of 100-percent silicone, each separated by a layer of heat-resistant embedded fibers, giving it the durability to handle extreme underhood conditions on both coolant and air passage systems. Rated for temperatures up to 330F, it’s engineered to hold up under high pressure, making it a solid choice anywhere boost pressure or hot coolant flow is a concern. Mishimoto backs this coupler, like the rest of its expanding line of silicone couplers, with the Mishimoto Lifetime Warranty.
Vehicle Applications
This is a universal-fit 90-degree transition coupler rather than a vehicle-specific part, designed to work across custom and OEM-replacement coolant and air intake system builds where a 3.2-inch to 3.95-inch outside diameter transition with a 90-degree bend is needed. It’s a practical option for fabricators and DIYers building or upgrading intercooler piping, coolant routing, or air intake plumbing on project vehicles.
