Oil Filter PF46 vs PF46 ??

[Harry S.]

Seems that not all PF46 oil filters are created equal. The original oil filter on a 2005/2006 was a PF46 88984215.

Now I come across a PF46 19256041. I cannot find it in the superseded list for the 88984215.

Anyone have an idea as to what the PF46 19256041 fits?

Thanks

Harry,

While not Professional vs Duraguard, this video link below explains the difference between the Professional and UltraGuard Gold Series.

I suspect the difference is along the same lines of good, better, best series.

Bill, could be. There are other PF46 filters with other part numbers that are for Trucks, GMC but not Corvette, thus the confusion.

Any AC PF-46 (except, apparently, the "ancient" larger diameter version shown in another recent post when used for a 1997+ Corvette application) should work fine for any application catalogued for a PF-46 filter. However, here's what I think applies to the 2 filters shown in your original post:

The PF-46 GM #19254061 is from the AC Delco "Professional" product line. This is an aftermarket product line. Thus, the 19254061 part number is uniquely applicable to that product line. The PF-46 GM #88984215 is an OEM product in the "Duraguard" product line. It was superceded by GM #19210283 and currently GM #12731172.

With rare exception, items in the AC Delco aftermarket product lines (i.e. "professional", "gold", "silver", etc.) have different GM part numbers ("long numbers") than OEM product lines and these part numbers do not follow the same parts history as OEM part numbers.

Nowadays, the GM OEM part lines have largely replaced the aftermarket product lines for many parts categories, especially things like filters.

So, what's the difference between an aftermarket product line and an OEM product line? In the case of the 2 filters shown in your original post, the likely only difference is the outside supplier that manufactured each and, for all practical purposes, the quality difference, if any, is negligible. Both use a cellulose filter media.

By the way, the UPF filter line is an OEM quality filter line that is actually used in some factory installed applications. These use a synthetic media filters. I've used them exclusively ever since they were originally introduced more than 20 years ago.

Joe, excellent.

Thank you.

So what is the visual difference in their appearance once you take them out of the boxes?

Different circle on the cap? Different flutes?

Inquiring minds want to know.

I believe the flute count is often an indication of the particular supplier to GM but I do not currently know how to "decode" it.

Once-upon-a-time all GM oil filters were manufactured by the AC Spark Plug Division. That ended a long time ago and now I believe several different manufacturers supply oil filters to GM and ACDelco.

Patrick, when I looked at the superseded list, I came up with 88984215 -> 19212083 -> 12731172 and now 12737094. The 19256041 did not appear in the list. Thus, my question.

When you take them out of the box, they look the same. Height, width, color exc. The only difference is the part number on the label and the font the part number is printed with.

But, as mentioned in the other thread on filters, the Service Replacement label looks nothing like the label on the filter installed on the line.

Even the blue appears a bit different shade?

Yes, from the line installed original the current Service Replacements (19256041 & 88984215) are slightly lighter, minor difference. But the 19256041 and the 88984215 Service Replacement are the same color.

We take the 3 point hit and move forward

Are there any original OEM PF46 filters available?

Do you mean assembly line installed, or OTC filters of the same configuration but the service label?

Assembly line ones are only if the original owner saved them.
OTC filters are available if you look hard, but of course the label is incorrect.
