Bronco AT-07446 Carburetor Manifold Flange Intake Boot ATV Powersports

The Bronco AT-07446 Carburetor Manifold Flange is an OEM-quality replacement intake boot designed to restore a secure, airtight seal between the carburetor and engine cylinder. Made from durable rubber, this flange mounts between the carburetor and the engine — not between the carburetor and the airbox — ensuring proper fuel-air delivery and eliminating vacuum leaks that cause hard starting and lean-running conditions.

Stock carburetor flanges are susceptible to premature failure from constant heat cycling, engine vibration, and exposure to the elements. Over time, this causes the original flange to dry out, crack, and develop vacuum leaks that directly impact engine performance. The Bronco AT-07446 is a direct-fit replacement engineered to OEM specifications, restoring proper carburetor support and an airtight intake seal.
