Is that why K & N filters cost so much?
Not completely sure on filtering capabilities on k&N filters compared to OEM however I usually change filters at least annually, To me anyway it's worth the extra cost to ease my four letter word removal frustration and messes I've made. and is usually same price or cheaper than OEM. I have also noticed more aftermarket filter manufacturers have started putting hex nuts on end of filters.

Never been fond of K&N filters simply because they pass dirty air when clean. You'll never find a big truck owner running them.

Certainly agree with you on K&N air filters but he's talking about K&N oil filters here.

Had a K&N on one of my bikes and twisted the hex end off. I do believe the oil filters are TUV certified but so are others. Far as air filters, never. That 'oiled' gauze might stop pea gravel but that is about it Only time a K&N will filter is when they are dirty. K&N claims a power increase on their air filters but that is because there is minimal filtering, if any on a new one.
In my opinion and experience as I'm sure most experienced folks know installing oil filters running a little bit of oil on the o-ring not only aids in helping seal it better on base but I feel it helps taking it off with conventional oil filter wrenches, that and not over torquing it of course helps in my shade tree mechanic experiences
Imo the key to using k&n air filters from occasional experience is cleaning and oiling them at least annually, apologies for the drift.

Dirtier the better actually. I have one on my 7.3 and I watch the filter minder and ignore the filter.
So you just add filter oil over the dirt? 7.3 power stroke is a great truck. Now I'm drifting like a UP snowdrift lol

Not at all. I watch the restriction and clean when applocable. Nothing more.

I've had bad luck with K&N air filters fouling mass air sensors on gas vehicles. That, coupled with poor filtration, high cost, and high maintenance makes me never want to buy their air filters again. I've been pleased with some of the high flow oil-less washable air filters on the market such as the afe line.
On several vehicles I have purchased the k&n kit to get the correct plumbing for the vehicle, then trashed the filter and purchased an oil-less one

One final drifting hack if folks have an oiled foam element like I do on ATVs particularly, I will continue to do it this way, that has worked for me over the years Is put the clean element in a one gallon freezer bag pour or spray filter oil in bag and move it around a bit, carefully, being cautious not to damage element. Not only is it virtually mess free but it gets sufficient oil on the entire element.

Oiled foam and oiled gauze are 2 different things. I do the same with my foam pre cleaners.
You have an aftermarket gauge or is it a factory indicator?

replaced the FoMoCo one with a Donaldson years ago. Same gage, same spring, different logo. The FoMoCo one broke off.

Nope I disagree. If you READ the instructions with these filters it clearly recommends NOT to use the nut when installing the filter. But everyone does anyways. So now that filter is too tight and upon removal the nut breaks off or is rounded. So unless the nut is ONLY used for removal….it’s fine
Imo I think a lot of folks don't clean the base off so if there's some slight seepage or even leaking caused by debris on the filters base so they torque it down way to much. In fact I remedied my folks car when they visited it was leaking oil all over my driveway not only was it way over torqued but the oil change place left the o-ring from the old filter on the base.Nope I disagree.

I’m talking about a filter with a nut welded on to it. Has nothing to do with dirty seating or not making sure that the old gasket has been removed. However those issues are certainly not good…
