I agree. The pleat spacing is pretty much meaningless. Because as you mentioned, they all have it. My criticism involving the K&N models is the silly, sheet metal "nut". As far as how they work once installed, I never had any issues with leakage. But I have never had any issues with ANY spin on oil filter leaking in almost 50 years of driving.

I may be over reacting, but I would expect for an oil filter that costs 3 times the price of a “normal” oil filter, it would be assembled with a bit more care and QC. If those wide pleats lay over, aren’t they more prone to tearing? I realize the torn media won’t enter the oil passages with a metal center tube in place, but I would like to get quality assembly for the premium price.

Show me one that's torn from being defective.

It's not meaningless on Purolators ... if you know what I mean. So it all depends on how susceptible the media is to bending and tearing under pressure of the oil flow through it. Of course, the full synthetics that have a wire or nylon mesh backing can get away with more pleat spacing because the backing keeps the pleats from deforming under delta-p pressure.
Bottom line - it's better to have good pleat spacing than not.

A little pricey, but not that bad really. Not out of line compared to others like Fram Racing filters. Pack of 12 is less per and free shipping.

A pleat is a little wide when you can write on it.

This whole thing about pleat spacing is silly. Because the only way you'll ever know if a filter does or doesn't have "proper" pleat spacing, is to cut it open and look at it. And who in their right mind cuts open every oil filter they use?..... Let alone AFTER they use it, when it's too late to do anything about it. And as I said, if you did you would most likely find they all have it to one degree or another.
These things are all mass produced on a robotic assembly line like soda cans. They have to be for how little they charge for them, and still turn a profit. Think about it. If Wal-Mart can sell a popular, brand name oil filter for $3 or $4 bucks, and make money doing it, how much did the factory let it go out the door for?

When certain filters show repeated failures of torn media due to brittle media combined with wide pleat spacing, then it ceryainy is valurble information to cut every filter open after use.
Maybe you don't hang out in this forum much, and have missrd all the torn Purolator reports over the last 4 yests.

This is why I randomly cut open new filters, brands and part numbers that I use regularly. If I see something I don’t like, I’ll move on to a brand that exhibits consistent quality and uniformity. So far, every used and new Wix and Ford Racing filter I’ve ever opened up has been on point. Note that I’m not referring to Motorcraft, but the Ford Racing filters.
All K&N Golds I’ve cut have been good up to this point. I am now either going to cut up the remaining K&N filters I have to look or just use them on my lawn mower and tractor.

So you've never seen a cartridge filter, or even learned what they are?

Imagine the heartache one might deal with if they cut open a filter that they used for "x" miles and discover how bad it is ! I've read posts from some here who buy (2) filters at a time, cut one open and if okay, use the 2nd one. Makes 'em feel good.... but the reality is, the one they put on could be the defective one.

Cutting open a new oil filter is a good way to discover if you like the internal construction or not. You might do this once for a given part number.
Cutting open a used oil filter is a good way to inspect what is being caught by the filter. This inspection may not be as good as pulling a valve cover or pulling the pan but it is relatively cheap, fast and easy to do.
Draining the oil into a clean drain pan and then decanting the oil can reveal junk that is coming out of the engine.
All these habits have some merit.
You might also know, the first filter I cut demonstrated the classical Purolator tear phenomenon. Thus the impetus for cutting every used oil filter.

Well stated. I cut open a new one every once in a while to keep ‘em honest, so to speak.
Sidebar; I just received 2 K&N HP-3001 filters from K&N today. The new ones have a threaded end bypass (which is what I would rather have), and the one I cut open had a Fram style plastic button in the dome end. Does anyone know who is making K&N’s filters now? It says made in USA on the new one. The one in the pictures that I cut up was from Mexico, and a couple years old.

All the K&N HP-1007 I have are Made in the USA and look identical to M1 filters. I've got them in new boxes and old boxes.
Yours sound like they're made by Wix.

I thought it was already known, but K&N has went back to Champ Labs production. Any Mexico production would be old stock.
Champ is making almost all of the HP and PS line, but I do not think they have the element business. That is likely still being sourced overseas. The Champ production is also not what they use for the powersports line which has also historically been sourced from overseas.
