I was comparing filters, looking for one with a little more size and I compared two Wix filters. The beta rating is different 21/37 for the 51348 vs 14/31 for the 51516, not sure what that means. Everything else pretty much lines up.
I generally gather that beta rating is a comparison of dirt entering the filter vs dirt leaving the filter. So how would these two beta ratings affect my engine? (99 Saturn SW1 SOHC 1.9) Hand waving logic says just go with the bigger one but what about the specs?
