Description
The Mishimoto MMCP-4090BL is a 4-inch, 90-degree coupler finished in blue, built as a connector piece within Mishimoto’s air intake systems lineup. Its precise bend allows it to link two sections of 4-inch intake tubing at a right angle, making it a practical solution for routing air intake plumbing through tight engine bay spaces.
As a foundational piece of any air intake system, a coupler like this one plays a key role in maintaining a secure connection between sections of a cold air intake or other intake filter setup. Whether you are assembling a custom cold air intake, replacing a worn coupler on an existing cool air intake, or reworking the layout of your air intake filter piping, the MMCP-4090BL’s 90-degree bend and 4-inch diameter make it a versatile option for joining straight and angled tubing sections where a clean fit is needed.
