Purolator Boss PBL3001 (Internal Bypass): Cut Open

[DoubleWasp]

I use a lot of PH8-equivalent oil fiters, so I thought I'd cut open the Boss equivalent and see wha we have going on inside.

Sorry for the ugly cut. All I had was tin snips and a hammer.

Don't say I never did anything for you.

New gunmetal can, sans grip:





Those of you who suspected the weight of the heavy Boss was in the baseplate, you are correct. It has a heavy and thick baseplate.







Oscar the Grouch was not home:



Good looking dress:



Bypass hasn't changed a bit:



Top end cap came off with bare fingers. Looke and felt like only this one dot here was holding it on:



Holes in center tube look tiny, but there is a lot of them:



Looks good here too:



And here:



Nylon backing was easier to tear than the media itself. Media is backed with a loofah.



Separated from the media, the loofah material is as easy to deform and tear as anything. Either the media is going to hold its own, or it won't. Nylon backing is not going to do it any favors.


Jerry's Final Thought:

Definitely not a relabeled PureOne.

Nylon backing seems effective as an advertisement only.

One mean base plate. To address what issue? Don't know.

Haven't measured media yet, but it goes from at least the floor to my ceiling.

I'd be willing to give one a go, but need more technical performance data first.

Center tube is an odd one, but may not actually restrict flow.

Overall, good looking filter (for whatever that's worth)

Run one for 5K miles and report back to us....

Thanks for all the hard work!

Thanks man!

Looks like the same material as what packing peanuts are made of. Interesting media to say the least. Instead of using wire mesh backing they used nylon. Sounds like Purolator still trying to cut corners.

Thank you for your contribution.

Nice photos.

Your contribution to advancing the knowledge of automotive oil filters is unmatched. I salute you!

Thanks for the photos!

I am going to have to ask you if you are drunk or joking? I think you are way off base here. I have stripped off some of the backing on the Boss I cut open, and it does support the media, and the media is more rigid with it than without it.

Glorified e-core?

Pleats look nicely spaced. Not sure what to think about the polymer backing material. It will probably be fine in use along with the louvered center tube. It may be they went to the louvered center tube just because of the new media design.

Thanks for the sacrificial cut & post!

How much are these?

Tell me that if the media starts losing integrity that the nylon is going to do anything at all for it. Don't make me take a video of just how weaksauce the loofah material is.

As I said before, the weak nylon does not a bad filter make. The Purflux filters I am so fond of have no backing at all. There's a perfectly good possibility that the nylon will never be put to the test. My judgement is against the nylon alone. The Boss could definitely still be an amazing filter.

List was $11.69 at my AAP. I didn't pay that much because I included it on a TRT30 order.

Even without the backing on the media the pleats are packed in tight, at least on my sample there was 61 total pleats. The center tube supports the media just like it does on other spin on filters, and my sample had plenty of glue to keep the pleat ends stationary. The backing is there to provide additional support to the media. Tearing the backing off, and doing what ever to it other than what it was intended to do is meaningless.

It's a different design that's for sure, but if you have a look around Mann is already using a similar design on Evotop fleece cartridge filters. If it did not work, I am sure it would have been pulled from the market by now.

Nice report, thanks.

Baseplate resembles the one off the Bosch Distance Plus, I'd be curious to see if the can thickness is similar as well. Has Purolator released any efficiency data on these? At a substantially higher price point than an Ultra, it would have to have awesome numbers before I would use one, & there have been Puro Synthetics that didn't look great after use.

That's the first Purolator I've seen in a long time that I would use. With Fram Ultra's selling for less I won't be buying these any time soon.

The baseplate is the same kind they have been using for decades. The bending forces on the center of the baseplate are tremendous when it's tightened. If over tightened it could cause the element to come loose. The can needs to be rigidly held also. Mercedes sells the Mann filters with the same looking element material, backing and all, with their logo on them. If it is good enough for Mercedes, who definitely test and are picky, it should be good enough for consumers. If the media is the same, it looks the same and is the same company making it.

And ice "looks like" glass.
