I can't believe how small the stock oil filter is.Which brand and what part # do you use in order to get the taller size filter

I use Mobile 1's version # MI-206, not sure what the #'s are for the other brands.

Off the top of my head I think the AC is a PF59 and the K&N is 2006 (think is actually HP2006). Just take note that some of the long filters hang below the front skid plate and oil pan. I tried the K&N on my last change and it has a 1" nut on the bottom, so that one probrably hangs lower than the M1 or AC.

I use this one too, just keep in mind it will hold about a 1/4 quart more than the stock size filters. It is longer.

Alright it's not working or I don't know what I'm doing so I'll try this.
Rank Brand Part Number
1 AC Delco Ultraguard Gold UPF58*
2 Mobil 1 M1-206**
3 Mobil 1 (Stock Size) M1-107
4 AC Delco PF58***
5 AC Delco (Stock Filter) PF44
* Larger than filter PF44 and offers better filtering than the PF58 (will hold 1/4 quart more of oil than the PF44 filter)

** Larger than filter M1-107 (will hold 1/4 quart more of oil than the M1-107 filter)

*** Larger than filter PF44 (will hold 1/4 quart more of oil than the PF44 filter)

I don't know if you can still find the UPF58. I use the long Napa Gold filter but I'm changing back to the short filter because my car is lowered and the long filter is a little to close to the ground for me.

I'm fairly certain that most if not all of the ACDelco Ultraguard Gold (UPF) line has been discontinued. I do have a case (6 filters) of brand new UPF58's I'm willing to part with. PM me if interested.

FWIW, my first choice would be K&N HP-2006, second would be Wix 51522/Napa Gold FIL1522.

I still use only 6 quarts with the longer filter.

I've used the AC PF58 in the past, but use the PF59 (anti-drainback or whatever it's called) now. It's basically like the stock filter but longer. I use a full 6 qts of oil. Trying to find K&N & Mobil filters around here is near impossible.
I can't rank all the filters 'cause I haven't used them all.

I've been using the PF59 with no problems - it's the one listed for the LSx truck motors and seems to be identical to the PF44 except for length.

I use K&N HP2006 and put 6 quarts of oil in. Works great so far. My car isn't lowered, so I can't comment on whether it would be something to worry about. It's definately not for me.
