isn't the A = extended performance? so should go more miles?
The normal 57045 is 6.30 also for preferred members on amsoil.com if you prefer that 8.30 I think for normal
I dont see the Wix 57045XP on the Amsoil site, only the 57045 which is $6.30I cut open my Amsoil EA017 and the filter media was held in place by black wire mesh that was molded along every single fold in the media. The filter says its good for 25k miles (I change mine every 2k miles) The quality on the amsoil filters seems way above anything else ive seen. I couldnt even get the filter media out. I should have taken a pic but I didnt.
Amsoil also sells the Wix 57045XP for only $6.30 for preferred members which is about half the price of the amsoil filter and also less than half the price of the wix that I've seen anywhere else.
I'd be interested to see if this is what replaces the PF63 now that the PF63E has more plastic in it.Upf designates ultra performance, not sure what GM used this on... Maybe a 1500 truck variant? Not sure. Either way I work on a few of my buddies new Tahoe's and this is what I put on the 5.3s. Still run the UPF48s on all my performance LS stuff.
