Description
The Mishimoto MMCP-R45-25275BK is a 45-degree black silicone transition coupler purpose-built to bridge a 2.5-inch inside diameter opening into a 2.75-inch inside diameter connection, giving fabricators and DIYers a clean way to route tricky bends in an air intake system or coolant circuit. Built from four layers of silicone divided by heat-resistant embedded fibers, this coupler is engineered to hold up where lesser hoses fail.
Whether you’re piecing together a custom cold air intake, rerouting an intercooler pipe, or plumbing a coolant line through a tight engine bay, this Mishimoto silicone coupler makes complex routing straightforward. Because it’s rated for temperatures up to 330F and built to handle substantial boost pressure, it’s well suited to sit right at the intercooler pipe connection on a boosted air intake filter setup, or anywhere a durable transition elbow is needed between two different pipe diameters. The 100-percent silicone construction resists the heat cycling and pressure spikes that plague thinner, single-ply hoses, making it a dependable upgrade over factory rubber couplers in both air intake system and cooling system applications.
Vehicle Applications
This 45-degree transition coupler is a universal-fit component rather than a vehicle-specific part, designed to work into custom intake, turbo, intercooler, and coolant plumbing builds across a wide range of engine bays. Because it steps from a 2.5-inch to a 2.75-inch inside diameter, it’s intended for builders matching those specific pipe sizes on their cold air intake, boost pipe, or coolant hose project, and it’s offered in black to blend into darker engine bay color schemes.
