I have a Craftsman rider with a Briggs & Stratton Intek Twin 21.5 OHV. The oil filter on this machine costs $10.00 (Carquest# 85056). I was told at the automotive part store that I could use another filter that has the same threads and the gasket is the same for about half the cost (Carquest# 85348). What is the difference in filters other than the part numbers and prices?
