In the e-core's defense, I've ran them up to 8,000 miles and cut most of them open. I've never seen a blow-through like a few have posted on here. All my high-milage 'cores were either STP or AC/Delco's. Most of the lower-milages ones I've opened were SuperTech's.
The last ST I cut (the one I linked to) was probably the worst looking of all - and one of the lowest milages. It may not have "failed" per say, but the pleats were so uneven at the seam, and had already folded over. Given enough time/miles that one could have turned ugly!
They all did their job though. Media trapped plenty of [censored].
