Purolator BOSS PBL11424 Virgin C&P, L11424 PL11424 PBL11424 Datasheets

I haven't seen any C&P or info on the part for GM's 2.7L Turbo 4 in the newer trucks, so I figured I'd contribute.

The datasheet for the boss claims 61 pleats (my sample has 60) and 799cm^2 filter area, but I measured only 670.36cm^2 effective/exposed surface area. Between the few mm lost in the endcaps, metal clamp, and the missing pleat, I think it adds up to close to the datasheet claim. At least it's rated better than the 46 micron rating of many of the other BOSS filters at 34 micron for 99%.

It seems well constructed. Some extra glue but nothing egregious. The media is consistently glued in place and the pleats are well spaced.

This is very helpful. That Boss is better efficiency than some others & is noted. It appears as though the Purolator Classic & Purolator One may be the same filter w/different paint jobs. If so the cheaper cost filter would be the better deal. Very good & thanks for posting this to this forum. Beautiful filter & Great first post!

I noticed that. I question the accuracy of these datasheets. Note the PBL datasheet incorrectly states the ADBV is on the outlet. And the PL datasheet stating it's a cellulose filter and identical in every specification to the L could be a duplication error. It would be odd for the line advertised as having a blend media to only have cellulose media.

Who knows but it's good data we have for now & until proven otherwise I'll accept its details. Be a good idea to make them aware of anything different or to understand their rationale of why they may show it a certain way on this spec sheet. Well, if you get your hands on a cheap L or PL to c & p to compare be sure to share their differences if any.

99%@23 microns would be better than any Purolator Classic I’ve ever heard of-that’s got to be a typo.

You know, I was thinking about this as I looked at various datasheets posted in the forums here. I don't feel like I have enough data to make this claim, but it's starting to form as a hunch - It seems like the Purolator filters with an internal bypass test worse for efficiency on their datasheets than ones without. I wonder if something about their unique design means some of the dirty oil can always blow-by.

Again, I feel more data would be necessary to show a solid correlation.

Actually, now that I looked at some more postings, I have a different idea. This PBL22500 is rated at the infamous >46 micron 99%, 22 micron 50% efficiency. But in the Ascent testing, it manages..... 34 micron 99% and..... 18 micron 50%.

Where have I seen those numbers before? Is the >46 micron/22 micron rating just a default filler figure they slap into the datasheet when they have no data for a given filter?

They use a metal-on-metal bypass valve, so yes there could be some slight leakage past the valve.
