I'm a first e-core user (2011 Silverado 4.3 V6), using the ST3387a instead of the PF47e since they look the same to me. What exactly are e-core advantages vs. steel core? Looking inside the filter it appears better flow. Is Chevy the only automaker using them as a factory part?

Better for recycling … no hanging chads on the unfiltered side … open flow … price

I use them about 5k-6k only

The plastic Center core doesn't bother me as much as the fiber end caps or the same as fram's low-cost filters

No real "increase in flow" (meaning less pressure drop across the filter) with an open eCore center tube since the media is the main flow restriction inside the filter.

If they’re the newer, smaller window ones, & have enough media, they’re pretty good, even good enough for GM (AC Delco Ecores). The older ones were not always great,I would avoid those.

I never understand this sentiment, the only separations and tears we've seen on here are with metal caps. I much prefer fiber (or no) end caps.

Yeah, I got my hind end roasted for ones I cut and posted. Hindsight is always 20/20

I don't think e-core has any disadvantage in theory (for 1 year, 10k OCI), but I remember some oil filters have unrelated torn media instead.

I haven't seen anyone yet to find a fiber end cap torn or rip on Fram or Honda, and Honda recommend changing oil filter on every other oil change.

I find the fiber ends on AC Delco filters remain intact every time … and the plastic is precisely mated with end parts

It seems like most pics of ecores posted here have very uniform filter media (no wide gaps) in comparison to some non ecore filters I've seen.

AC Delco E-cores are perfectly fine. Nothing to be wrong with them. I bought a case of 12 years ago and finally finished the pack off. No issues to report.

Count me of the same opinion. I believe it could be said that thinking gluing to metal end caps is any better than fiber end caps is, illogical.


For BITOG folks, ecore filters are much easier to tear down and analyze. Much, much easier.

I have run several eCores from Champion Labs, AC Delco and STP. All had straight pleats. The end caps were fiber and were attached very well. I never had any issues with them.

The end cap bonding process seems a bit different - but good …
