Maintain the rugged utility of your Jianshe ATV with this high-performance 30mm Intake Manifold. Specifically designed for the JS200 and JS250 engines, this joint provides a heavy-duty, airtight bridge between your carburetor and the engine cylinder head.

This premium aluminum and rubber replacement restores your engine's vacuum integrity, fixing erratic idling and ensuring peak power delivery on the trails.
