The PF46"e" is the improved version of the PF46.
ACDelco has announced a redesigned Original Equipment (OE) oil filter that offers ACDelco's exclusive Duraguard® media in a smaller package.
ACDelco has announced a redesigned Original Equipment (OE) oil filter that offers ACDelco's exclusive Duraguard® media in a smaller package.
The new OE filter applications PF46E, PF47E, PF52E and PF61E will be installed in applicable new GM models.
The new oil filter features:
Increased efficiency and higher burst and collapse strength (Fig. 5, A)
A new Nylon core that provides better flow characteristics and improved collapse strength
(Fig. 5, B)
A full cover baseplate that allows easy installation in blind applications (Fig. 5, C)
Duraguard media, ACDelco's trademarked synthetic cellulose-blended media that
efficiently filters particles as small as 10 microns -- 1/3 the width of a human hair -- to
ensure a clean supply of oil to engine components (Fig. 5, D)
A combination relief and anti-drainback valve that prevents dry starts and assures oil flow
(where applicable) (Fig. 5, E)
In addition to the new OE design oil filter applications, the original filters (PF46, PF47, PF52 and PF61) continue to be available in a classic design.

"Improved"??
Taken from a Silverado/Sierra discussion forum. You be the judge.....
"E-cores" (the filters with the "E" suffix) use cardboard endcaps, verses an endcap made from other materials, that might not be as easy to recycle. There are other differences as well".
If this is indeed accurate, then it appears that the EPA is reaching even further into the automotive field, and interested more in landfills, than the longevity of our vehicles.

*ATTENTION AC DELCO OIL FILTER USERS*
AC Delco has changed how they manufacture their oil filters! All filters ending with the prefix "E" have plastic internals instead of the original metal!

Wix 51042 (gold) or 51042XP (Extreme Duty).
Acceptable (the same filters, "house branded") Napa 1042 (Gold) or 41042 (Platinum, equivalent to 51042XP).
The C6 I work on gets the Platinum/XP version always.

There are millions of Delco filters in use, they meet or exceed specifications and they are recommended by the manufacturer. I have always used Delco on my GM products and Motorcraft on my Fords. I know some people think they are oil filter experts (how does one become a filter expert?), but I will stick with what works for me.

Wow! Being a new forum member I am amazed at the answers to a simple oil filter question. I love it!
But, I wonder what kind of responses a person would get if he asked what kind of toilet paper was the best?
Me, I used the PF46E filter on my 2003 C5 and Scott tp on the other. So far, both receiving units are still functioning flawlessly!
