I cant remember if the number got changed for LS1 Did AC change Oil Filter number from PF 44 to PF47?
Thanks....

 

back up top

 

yes it did change to either 46 or 47 (i just went blank, but i think it was to 47 though)

 

I'm pretty sure it's a 47, they can look it up for you at autozone. I personally use the truck filter. Either for the 5.3 or 6.0 Silverado. It will fit, but it's a bit more surface area on the filter.

 

Ok Thanks alot guysI thought so,I got one tonight at Murrays,I looked it up in the book ,but it wasnt updated it said PF44 ,I was in a hurry and the line for service was way to long.So I just was going by memory and grabbed the PF47...

 

The PF47 won't fit, that is the one for the 3.8 V6. The new AC filter for the LS1 is the PF46.

 

yeah, i questioned the parts guy when he gave it to me, and he said yes they did change it to 46; different valving perhaps?

 

Ok,Back to Murray's to change the 47 to a 46,I guess Haste makes waste...Thanks for the info

 

Yup, its a PF46:

I like how you can look up a lot of things on Autozone's Site.

 

pf46 or pf59 for a longer version

 

Ah, now that's good to know. It's like the old PF35 and PF35L for 3rd Gens

D

 

yup, id much rather have a little more filter area and capacity

 

Or you can use the UPF44...the higher grade PF44. Ultra Guard PF44. Much better IMO. Or the PF59 which is the longer of the 2.

 

Yep, the PF59 is the long version

 

Thanks for the Info,on my next oil change I might give the longer filter a try,a little more filteration wouldnt hurt

 

I don't know about now-a-days but back then the PF35L's were actually cheaper than the PF35s that would be great if it was that way with the PF59
