Stay away from Delco E-core filters, They are junk!, E-core filters generally have a "E" suffix....PF61E for example. Look down in the filter, If you see a plastic media support...It's an E-core, Metal support...Classic design.

Thanks for the info. on the "E" AC Delco filters....did not know about the design change. Wix for me from now on !
