The Mishimoto 2.5 Inch Blue 90 Degree Coupler is a 2.5-inch, 90-degree coupler designed to connect compatible components in an automotive intake or piping system. Its angled shape supports routing where a straight connection is not suitable, while the 2.5-inch size identifies the connection diameter. Finished in blue, it provides a distinct appearance within an engine bay. The coupler is supplied by Mishimoto under part number MMCP-2590BL. The available product information does not specify its material, wall construction, pressure or temperature ratings, or included clamps, so confirm those requirements for your application before installation.
No vehicle-specific fitment, engine, chassis, or compatibility details are provided for this coupler. It should be selected for systems that require a 2.5-inch connection and a 90-degree bend, with the intended mating components and routing verified before purchase. The source does not identify a particular vehicle, use case, installation method, or whether additional hardware is included. Accordingly, fitment should be determined by comparing the coupler’s stated diameter and angle with the dimensions and layout of the existing or planned piping. This information alone does not establish direct-replacement or bolt-on compatibility for any specific application.
