Product Description
Genuine OEM Eskimo 300478 Windpipe Intake for 43cc & 51.7cc Viper® Engines
Restore the power and reliability of your Eskimo ice auger with the genuine Eskimo 300478 Windpipe Intake. This crucial component, also known as an intake manifold or intake boot, forms a perfect, airtight seal between your engine's carburetor and the cylinder. It is precision-engineered to deliver the optimal air-fuel mixture required for peak performance, easy starting, and a stable idle.
Over time, the original windpipe can develop microscopic cracks or become brittle due to temperature cycles and fuel exposure. A compromised intake is a common cause of hard-to-diagnose engine problems, including high revving, bogging down under load, and difficulty starting. Replacing it with this genuine OEM part ensures a perfect fit and restores your engine's factory specifications.
