ENGINE MOUNTED OIL FILTER KITS AND RELACEMENT FILTERS SSP-885-2
Clean engine oil is essential to long engine life. Full-flow filter elements and full-flow spin-on assemblies are an added improvement over older methods of filtration and can be installed on any applicable engine not equipped with a filter.
Installing an oil filter on an engine not equipped with a filter can increase the oil change interval from 25 to 50 hours.
