Oil Filter
The oil filter catches large particles that might damage the generator if left unfiltered. The Onan HGJAB oil filter allows oil to bypass the filter during cold starts or if the filter becomes plugged.
Air Filter
Air filters remove dust, pollen, mold and other contaminants from the air in the RV's ventilation system. The HGJAB filter is higher-density than most filters to work effectively for the high-use RV environment.
Fuel Filter
Fuel filters block dirt and rust particles from entering the fuel to avoid contamination.
Spark Plug
The spark plus ignites fuel via an electric spark to provide power to the generator.
