EcoGuard X4651 New C&P

[GriffinB]

I bought this filter because it was on wholesale closeout at RockAuto, and I already was buying closeout parts. For $1.22 from Famous Brand I can't complain, and I don't see why this filter wouldn't work for a normal 5k OCI. This filter does look the worst out of the other two closeout filters I purchased.
It was made in China.
New EcoGuard vs a Pronto PO4651EX. A very big height difference.

This is a Pronto PO4651 vs the X4651. This is the "same" filter and interchangeable, but the X4651 sure looks small. I'm sure it's fine but I would never run it.

At least there are plenty of pleats and they are even.

Thanks for the compare of these filters.

Could you cut out the filter media and measure? Sometimes they can pack in more media in a short cartridge with deeper pleats. Doesn't look likely in this case but I'm curious.

Is that a genuine Longacre Racing Products filter cutter, or is it one of the numerous copies without the Longacre sticker?

$55 extra for the sticker.

The media area can be calculated by making two measurements and counting the pleats. Just need the right scale to measure how deep the pleats are. Here's an example.

Seam was glued, and I verified it was totally glued on the whole pleat width by trying to separate it (shown gap). Total pleat count was 58 including the seam. But since it was totally glued, then there were 57 pleats filtering oil.

The easiest way to get the total media area is to measure the pleat length and depth, along with total number of pleats.
The pleats were only 3/8" (0.375") deep and 2.75" long. Just use a thin mechanic's scale similar to the one shown. Much easier and cleaner than cutting the oily media out and stretching it out somewhere.

Total media area is...

Both look good for 5K OCI's. Holes in the center cores, and no glue protruding. I'd run either one in my beaters.

Haha hell no, this is a cheap one off of amazon and has worked well enough. Sadly it does not go small enough for the PG4612EX filters.

Even with the two rollers in the holes closest to the cutting wheel?

I didn't even thing that I could move the two bearings to those holes, I'm sure they would fit then. I wonder how many used PG4612EX filters I still have...

Those closer holes for the two rollers are for cutting smaller filters.
