Description
The Mishimoto MMCP-4SBL is a 4-inch straight coupler finished in a bold blue, engineered as a connection component for air intake systems. As part of Mishimoto’s air intake systems lineup, this coupler is identified by part number MMCP-4SBL and is built specifically to join sections of intake tubing that share a common 4-inch diameter.
A well-fitted coupler is a small but essential piece of any cold air intake or air intake system, sealing the gap between components so air can travel efficiently from the filter to the engine. The Mishimoto MMCP-4SBL brings a clean, color-matched blue finish to that job, making it a practical choice for anyone assembling, upgrading, or servicing a 4-inch air intake setup and looking for a coupler that fits their existing cool air intake plumbing. Whether you’re routing a new intake filter housing or tying together custom intake tubing, this straight 4-inch coupler is designed to complete that connection.
Vehicle Applications
Because the MMCP-4SBL is a 4-inch straight coupler rather than a vehicle-specific kit, it is built to fit any air intake system that uses 4-inch diameter tubing rather than being limited to a single make or model. This makes it a flexible option for connecting components in a variety of cold air intake and air intake filter setups that call for a straight, 4-inch connection point.
