Hi all! I see advance auto has a ac Delco professional duraguard..ph 47. Non score.which is cool.i don't like e cores. It's listed as being 98% @ 25-30 microns efficient.EastcoastGM,best value..GMpartsdirect. they have GM authentic ph47. The skus are different between duraguard which is 19210284 and authentic 25010792.
Would the GM authentic be better,or same as the duraguard? Efficiency,quality,everything!?
