Description
The Mishimoto MMCP-R45-3540BK is a black 45-degree silicone transition coupler built to bend coolant or air intake system plumbing around tight engine bay obstacles without giving up strength. Constructed from four layers of silicone divided by heat-resistant embedded fibers, this coupler carries a maximum temperature rating of 330°F, giving it the toughness to survive extreme underhood conditions.
Routing custom intercooler piping or reworking a section of your vehicle’s air intake system often means dealing with awkward angles that stock rubber hoses simply weren’t designed for. This Mishimoto silicone coupler solves that problem by offering a dedicated 45-degree transition elbow shape, letting you connect mismatched diameters while keeping the bend clean. Because it’s rated for substantial boost pressure and built for both coolant and air passage duty, it works equally well on an intercooler pipe connection or a coolant line that needs a smoother path. The 100-percent silicone construction outperforms typical factory rubber under repeated heat cycling, helping the coupler hold its shape and seal over time. This listing is for the black colorway, part of a lineup also offered in blue and red so it can be matched to the rest of an engine bay.
Vehicle Applications
This Mishimoto 45-degree silicone transition coupler is a universal-fit component sized with a 3.5-inch inside diameter on one end and outside diameters of 3.7 inches and 4.2 inches, making it suited to custom air intake system or coolant plumbing projects where a 45-degree bend and a step between hose sizes are needed rather than a single vehicle-specific application.
