So my quoted post early in this thread stands as posted and accurate. And apparently not only is not "clear," it is patently false. And really it leads me to ponder again why anyone would make such a statement with no proof whatsoever.
As for the Silver line that is not the topic of this thread so it's exploded view is irrelevant. That and 'some' (not all) Silver line dissections with combo valve have been shown numerous times here, and it is made to Napa's spec for that line.
As a little research of this site would show, the pics are basically redundancy to all the pics and information posted on this site previously. Imo, a shame to waste good money, if that's what was done, on cutting open useable filters to confirm what was already established.
As for thread end bypass, even if found it too is irrelevant to the combo valve combo claim as it's still separate bypass only it uses Wix traditional thread design as opposed to the dome end bypass shown in the the XP/NP cutaway and confirmed by the linked bitog poster threads. That said as my posting on the previous page showed, dome bypass was found in said XG/NG application.
Thanks for confirming what research here already showed as stated and linked in my posts.

This is at least the second time recently that you have posted this bogus information as regards the topic'd WixXP/(NP) and now Wix/(NG) branded/labeled filters. As I said previously, I'm not sure from whom or where you are obtaining your information (though I think I have a good idea because I've read the same inaccurate information posted on other message boards and youtubes by a recognizable poster), but it is incorrect.
No current Wix branded/labeled automotive application filter uses a combo valve. And no WixXP or NapaPlatinum uses a combo valve either. The Wix XP and Napa Platinum line use separate dome end bypass.
Also again, if you have an authoritative link proving the combo valve allegation post it up. Otherwise I take this to be nothing more than unproven internet tripe posted with an agenda......
