I was wondering if anyone might know, if the correctAC Delco oil filters for my '03 Silverado w/ 4.8L is the PF46. My wife has an '02 Avalanche w/ the 5.3L, i was told they both take the PF46. Anyone know for certain?

 

yes that is the right filter

 

Same filter but I would get a better filter, I like either carquest premium or k and n filters

 

i dont know about that carquest filter but you cant go wrong with the k&n filter. but then again there is nothing worng with the PF46 that is the filter that it comes with from the factory so that much say something for it

 

Thanx all for the replies, one of the denotes on a filter book was something about a checkvalve, and i weren't sure if they had it but when they come from dealer / manufacturer w/ AC Delco's, then i guess it is the right one. Jim

 

Is CarQuest's premium the Wix filter? I know that's what Napa and O'reilly's sell as their premium filters and most of the locals that seem to know anything about cars prefer them. I on the other hand haven't noticed much of any difference between that and a good ol' Wal-Mart Fram oil filter. I did however splurge and stick a Mobile 1 oil filter on it last time though.

 

stick with the pf46..ot has anti-flowback valving in it...i'm sure others do also..but i dunno which ones

 

I wouldn't go all fancy with the filter. AC Delco will work just fine. Just don't buy junk off-brand one.

 

I like the napa performance filters though havent seen really a difference between them and the nicer hastings oil filters Im used to. But never can go wrong with OE AC Delco or the K & N.
