Description
The Mishimoto MMCP-4045BK is a 4-inch, 45-degree silicone coupler built from 100-percent silicone with heat-resistant embedded fibers, giving it a maximum temperature rating of 330°F. This elbow-style coupler is offered in black, and Mishimoto also produces the same 45-degree, 4-inch design in blue and red for builders who want to match their engine bay color scheme.
Whether you’re piping together sections of a cold air intake, routing a cooling line, or fabricating custom air intake system plumbing, a durable silicone coupler like this one is a key connector between rigid tubing. Because it’s coolant compatible, this coupler isn’t limited to air intake duty alone; it can also be used in cooling system applications where a 45-degree bend and high heat tolerance are required. The 100-percent silicone build with embedded reinforcing fibers is designed to handle the heat and pressure swings that intake and cooling system components see, making it a practical upgrade over degraded factory rubber elbows for anyone building or repairing a cold air intake or air intake system setup.
Vehicle Applications
Mishimoto does not list specific make, model, or engine code applications for the MMCP-4045BK, so this coupler is intended as a universal-fit component for custom intake, turbo, or cooling system plumbing rather than a vehicle-specific part. Its 4-inch, 45-degree elbow shape makes it a versatile choice for fabricators and builders working on a wide range of custom cold air intake or cooling setups where a defined bend and diameter are needed.
