Product Description

This intake manifold bellows (intake boot) is a genuine OEM Husqvarna replacement designed to connect the carburetor to the engine cylinder and seal the intake system. Made from durable rubber, it helps maintain the correct air-fuel mixture and prevent air leaks, making it an ideal replacement when a cracked or hardened boot causes poor running, rough idle, or starting issues.
