Description
The Mishimoto MMCP-3090BK is a purpose-built 3.0-inch, 90-degree silicone elbow coupler engineered for custom piping and cold air intake system builds. Molded from 100-percent silicone with heat-resistant embedded fibers, this black coupler is designed to handle high heat and pressure while making tight-radius connections in intake, intercooler, or coolant piping runs.
Whether you’re fabricating a custom air intake system, replacing a worn factory coupler, or connecting universal piping in a turbo or intercooler setup, this 90-degree silicone coupler gives builders and fabricators a durable, flexible connection point. Its silicone construction resists the heat and pressure swings that stress lesser rubber couplers, and because it’s coolant compatible, it can also be used in cooling system plumbing where a tight elbow bend is needed. Mishimoto backs the coupler with its Lifetime Warranty, so it’s a long-term solution rather than a one-season fix for intake or piping projects.
Vehicle Applications
This is a universal-fit silicone coupler rather than a vehicle-specific part, so it is not tied to a particular make, model, or year. Instead, it is intended for use in custom cold air intake systems, aftermarket piping kits, and intercooler or coolant plumbing where a 3.0-inch, 90-degree elbow connection is required. Mishimoto notes that when using this hose, it should be paired with appropriately sized hose clamps and universal piping, which are sold separately.
