Description
The Mishimoto MMCP-4090BK is a 4-inch, 90-degree silicone coupler engineered to link sections of tubing in an air intake system at a sharp elbow angle. Molded in black 100-percent silicone with heat-resistant embedded fibers, this coupler is built to handle high heat and pressure under the hood, and it’s backed by the Mishimoto Lifetime Warranty.
Whether you’re piecing together a custom air intake system, swapping out a cracked factory rubber elbow, or connecting an air intake filter to your piping, a dependable coupler like this one is what keeps a cold air intake, cool air intake, or any other air intake setup sealed tight. Because the MMCP-4090BK is coolant compatible, it can also be used in coolant routing where a 90-degree silicone connector is needed, giving builders of cold air intakes and air intake filter assemblies a flexible, heat-tolerant elbow that stands up better than a worn stock rubber connector.
Vehicle Applications
The MMCP-4090BK is not built for one specific make, model, or engine — Mishimoto designed this 4-inch, 90-degree silicone elbow as a universal fitment piece for use wherever a connector of this diameter and angle is required. That makes it a practical option for custom air intake system builds, intake piping repairs, or any car, truck, or SUV project that calls for a 4.2-inch outer-diameter silicone coupler bent at 90 degrees.
