WOW! Thanks ! The Wix 51675 (NAPA 1675) filter that is $36 at NAPA/O'Reilly's is only $13.28. The Wix 33397 (NAPA 3397) that is $17 at NAPA/O'Reilly's is only $6.84 there !I recently bought some oil filters from usafilterstore.com. NAPA charges something like $35 for a Fuso oil filter. I think they were $12 or $14 from that source.
