Air Cut-Off Valve Set - Each

The K&L Supply Air Cut-Off Valve Set is designed to prevent afterburn caused by a lean fuel mixture when the throttle is closed. It temporarily blocks the slow-jet air passage, instantly creating a richer fuel mixture. Each kit includes all necessary components for a complete rebuild, including a diaphragm, spring, and O-ring. This set serves as an affordable alternative to OEM assemblies and is compatible with various OEM part numbers.
