So, tonight has been a fun night.
What I thought was going to be an easy time cutting open some oil filters turned into a hassle, FWIW those that hate on Korean made MANN+HUMMEL filters need to hear something.
It took a total of 20 seconds to open this Purolator Classic with an OF Cutter. It took almost an hour to cut open this OEM Hyundai filter. Why? Well, I ended up breaking the oil filter cutter, 4 hacksaw blades, as well as a Made In USA steel can opener while trying to cut this beast open. It finally took a pair of tin snips and some strategic use of my last hacksaw blade to open it. You will see in the pics below some gnarly photos of American Made Purolator versus a Korean Made OEM, who oddly enough are both under the MANN+HUMMEL umbrella.

Enjoy.

So, as you can see, they are both filters, of the oil variety, take these comparison photos of the exterior styles to heart.

The Purolator was a later model, with the louver style center holes, where as the OEM filter has the OEMs dang logo on the inside, oh and it has these big holes that look akin to a Mahle filters holes IMO.

Interestingly enough, the baseplate of the purolator actually broke in half upon opening, and its got a good amount of rust where the two pieces making the baseplate met, probably the weld rusted out? Who knows, it broke and is rusty

The media on the OEM filter is pretty even throughout. Ignore the endcap cut in the seam photo as well as the blood, tin snips are fun, adventurous, and slightly dangerous. The media on the OEM looks pretty nice.

The purolators media was purolator media to a nutshell. pretty even until the seam side, then typical sloppiness occurs, media had no visible tears throughout, which is good.

Springs are different, way different, figures as the OEM was designed for flow and the bypass pressure is a different spec in comparison to the purolator. ignore the snip in the end of the OEM spring, again Tin Snips can get kinda wild sometimes, especially with carpal tunnel. OEM is on the Right, puro is on left.

Date/Lot code included for purolator, purchased it a long time ago on clearance at WM. It is cross-referenced to the OEM filter FWIW

The only thing that I am concerned about is the Purolators baseplate splitting into two pieces, and the rust. If that snapped while installed, the entire filter possibly would have been gone and the engine woulda dumped everything and more than likely seized. More than likely it was due to age, or the conditions it was in at walmart (Garden section clearance aisle) as I keep my filters literally in my clothes closet (climate controlled, dark environment/no direct sunlight) Anyway, the one I bought with it (in 2016?) (another purolator classic) was literally put on my old car a few weeks before trading it in for the truck in my sig, hope the dealer changed the oil even though it didnt need it for another 4800 miles (5000mi OCI)



FWIW, there is a Hyundai TSB to only use OEM on some Hyundai engines, including the 1.6L Turbo that my old Veloster had. Despite what I see here, I still wouldnt hesitate to use a purolator product (shoot I am as we speak and wont lose sleep), as these are both MANN filters, and appear to be well made (minus the rust mentioned, which I do believe is more than likely due to storage at Walmart, next to potting soil on clearance, in a humid outdoor greenhouse thing, I doubt its a purolator factory issue)

These were the last two filters I had on hand for my old car, so congrats, I donated the time, effort, thumb skin, broken oil filter cutter, broken made in usa can opener, and 4 broken saw blades, to some online oil filter nerdiness.

P.S. if you wanna donate to the "I need a new oil filter cutter, can opener, and hacksaw blade" fund, let me know, it would be much appreciated.

Two things stand out about the Purolator filters that contribute to the media tears. Notice the wide pleat spacing where the media is joined and the gap between the media and end plates. The Hyundai filter media is nicely mated to the end plates. The glued media to end caps are shielded by the lip on the end cap. Purolator can do better.
 
I don't recall ever seeing the large difference in diameter and thus the radial gap between the media O.D. and the end cap turn up.

That rust is bothersome. It is now a iron oxide abrasive.

The rust formation May be a storage/climate issue; i.e, the Flood waters were only up to the second shelf and these were housed on the third.

I usually did buy them, as the Hyundai OEM filter can be had for
Either way, I know theres people out there hesitant to use other brand filters that are made in Korea, if they're anything like these, I'd have no problem using them.

Puro 14459 were(are?) like that; I've cut a few.
