Exposed! Filters in the buff....

[The_Eric]

So I finally got around to cutting open several filters that have been taking up room on my bench.

Not pictured is a Wix 51775 for a Ford 4600 diesel tractor. It was flawless...


First, the group shot. From the left:

-Motorcraft 820s on a 2007 F150/5.4/87k miles. It was on there for ~1500 miles but around a year and a half using MC 5w-20. ADBV was silicone and very pliable. Pleats were wavy in places - moisture?

-Next is a Parts Master (second line Wix) 61372 from a 2005 F150/5.4/unknown milage. Oil was also unknown. ADBV was nitrile? and not very flexible. Pleats were less than the first line Wix and appeared to be thinner. Was also wavy..

-In the middle is a Wix 51372 from a 2002 Town Car/4.6/60ish k miles and about 6k miles on MC 5w-20 ADBV was silicone and in good shape.

-OEM Hyundai filter on a 2001 Hyundai Elantra. Vehicle mileage is around 60k and the oil was Amsoil SSO 0w-30 for around 6k miles. Silicone ADBV was working properly and flexible.

-Next is the much despised e-core (PF-47). Car is a 95 Grand AM (3.1 V6) with 250+K miles. OCI was 4 or 5k miles on PYB? I was expecting the worst, but really this thing was fine. Pleats were uniform, no tears and lots of pleats... The end caps didn't come off without a fight either. Combination valve seemed to be in good shape. Also worth noting is that when I took the picture, I had already wrestled off one of the end caps.

-Last is another PF 47 (classic) on the same Grand Am. 4k oci on Mobil Clean 5000. All I can say is wow! This thing is built very well with lots of pleating. it held up very well. ADBV was nitrile and still quite flexible.

Next, a little closer shot. From left: OEM Hyundai, e-core and classic

Thanx for posting!

Definitely like the look of the Classic better than the E-core. Looks like a solid filter.

thank you! the first filter im guessing moisture... but nothing bad from the engine. i would guess it has to do with sitting a year and a half and only seeing 1500 miles. perhaps alot of short trips?

any mileage/time info on the 2nd (wavy) filter?

other then that, they all appear rock solid!
also, do you know where the non e-core ac delco was purchased??

Jake, your thoughts are the same as mine on the first one - short trips.

The second filter, if I had to guess has about 2500-2700 miles on it and in the neighborhood of 3-4 months.

The AC Delco PF47 Classic can be bought at Advance Auto. This is actually the first of two and I really don't know where I got it... The second is on the car now and was bought at AA.

cp3: Yes, I like the looks of the classic better than the e-core as well, but really it did it's job well. Like Jake said, it's built solid as a rock!
