781028 Voes Plugs Dealer Pack of 5

These V-Twin VOES plugs are designed to seal the vacuum port on a Harley-Davidson intake manifold when the Vacuum Operated Electric Switch is removed or not required. This is a common modification when switching to certain aftermarket ignition systems or performance carburetors that do not utilize the factory vacuum advance signal. Manufactured from a durable, heat-resistant material, the plug ensures an airtight seal to prevent vacuum leaks that could lead to poor engine performance or lean running conditions. It is a simple yet critical hardware component for riders fine-tuning their intake tract. V-Twin provides these as a direct solution for maintaining manifold pressure integrity during custom engine configurations.
