This standard replacement air filter element is designed for Hyosung motorcycles with carburettor systems. A blocked or overly dirty filter disrupts the fuel-air balance and leads to rough idling, sluggish throttle, and poor fuel economy—it can even foul your spark plugs over time.

🔧 Install Tips & Advice

Service Interval: A safe change range is every 5,000–10,000 miles. Off-road use or heavy traffic may require earlier changes.
Clean the Airbox: Always wipe out the inside of the airbox with a clean cloth before inserting the new filter to ensure no debris enters the intake ports.
Proper Seating: Ensure the filter seats evenly and properly within the airbox to avoid unfiltered “dirty” air bypassing the element.
Pro Tip: For the full benefit, perform this filter change alongside new spark plugs and a carb clean to restore crisp performance.
