TIP:
Air Filter helps eliminate contaminating of dirt, dust and debris from the carburetor and engine. It provides excellent protection against ingested dirt, improves airflow and prolongs engine life by providing clean filtered air while running.
A dirty air filter can cause the engine from not operating properly. The air filter should be checked if the engine drops in power. We recommend replacing your filters every 3 month for best performance.
