Been using K&N HP filters for a while. Sometimes Wix/NAPA Gold when it’s easier, and sometimes For Racing FL-820S on the Marauder. Cut open an unused HP-3001 that was a “place holder” on the Torino. Pleat spacing is pretty ridiculous, in two spots. I noted the two spots in pen, they are 180 degrees apart. I’ve decided to use an FL-299 equivalent NG 1773 on the Torino, since they are bigger and have all the right stuff. (Silicone adbv, thread end bypass). This cut open K&N has me not feeling so hot about K&N lately. Think I may just go with NAPA Gold or Ford Racing FIlters from now on on the entire fleet. Sent an email to K&N with pics. We shall see what they have to say.

My biggest gripe with K&N oil filters is the cheap sheet metal "nut" they spot weld on the bottom, to assist in removal and installation. It's why I bought the filter in the first place. Even a 6 point socket will slide right off the thing, because they have the top of the flats so rounded off. And there is so little bearing surface on the "nut" itself for the socket to grab on to. (You have a good view of it in the second to the bottom photo).

It would have been a 200% better idea if they had just spot or tack welded a cheap, mild steel 1/2-13 or 5/8-11 nut on the end of it, and charged a few cents more. I hate when companies have what appears to be a good idea, only to have it become worthless due to poor execution.
 
I see no reason to buy K&N oil or air filters. A NAPA gold oil filter is a better filter and less money. And the K&N air filter is just a poor design that lets in a lot of potentially dirty air.

I like the idea of using better flow K&Ns from November 1st to March 31st, here in cold Michigan. The other six months OCI, I will be using a Wix/Napa Gold/Fram TG equivalent for better filtering.

What ever floats our boats, in the manner we want it floated.

Isn’t airflow into the engine controlled by the intake butterfly and the mass airflow sensor? Unless you’re running WOT how does that matter?

This one is USA. I guess Champ Labs? It is a perforated center tube.

Been looking at lots of cut open Wix/Napa Gold filters, like what I’m seeing. May even buy one to chop up myself to see first hand, in my particular part number.

Also very tempting to chop up the remaining K&N’s to see if this is a thing.

Funny thing is the Santa Fe uses a cartridge filter, and the K&N PS-7022 cartridge looks very good. Every time. Perfect pleats and straight.

There have been reports that oil leaks can happen where the nut is spot welded to the can. I use to run K&N oil filters on by bike, but no more. Race tracks won't let you run a K&N because of the oil leak risk at the nut spot welds.

Amen brother. They are junk for sure.
 
Am I the only one that had never had a problem with the nut?

You only use it if the filter is stuck; a filter should come off just fine by hand. The nut is nice if you need to give the filter a bump to loosen it.

To the pleat spacing - we've seen this with every brand I can think of. Even the Ultras have some wide pleats from time to time.

Weather influences cold start behaviors. Age/condition of filter influences it also..... and that plays-into-it / matters. Even a dirty throttle body that partially clogs injectors will change how your engine starts cold and that changes how your fast idle upon cold startup influences flow.

While I'm at it, lets add high efficiency fibers in that filter. There are reasons why people choose K&N for racing / high-rev engines. I want a below freezing filter on cold start that gets oil up to the top in the least amount of time. You stick with your Ultra and I'll stick with K&N Premium. I am first & last owner of all my vehicles. So perhaps I care more about extended engine life than you. I have almost seven months of using a more restricted filter. I don't need 12 months of it and my engines enter junkyards 18 years later with vehicle-body rusted badly, but the engine runs like new - doesn't use more than a quart in 5-6K and the dipstick is generally clear oil at that junkyard...... all between 250-300K on the odometer.

If I lived in a non-salted road state, Id probably always reach 400+K easy..... with never even taking valve covers off in the lifetime of that vehicle. So please never tell me I do something wrong / incorrect.

Yes, very irregular pleat spacing in Fram Ultra cartridges I've seen ... whereas their Chinese-made Tough Guard equivalent cartridge has admirably even spacing. Why?

K&N oil filter cartridges I can find are Korean. K&N's claim that they minimize restriction leads to doubt about their efficiency, at least to me.

PD oil pump makes a few PSI in delta-p between filters a non-issue.

Which cartridges are efficient?

It's possible to have high efficiency and low restriction, but I'd have to see test data from a manufacturer to prove it with measurements.

They don't claim to be (or look like) synthetic media. However, none of that matters, when the media is such a pretty pink color.
 
The yellow PureOnes were very efficient and flowed very well (data given by Purolator), and those weren't synthetic media. It all depends on the design and total area of the media.
 
Going back to these on the Marauder. They are hands down the most bulletproof, beautifully assembled filters I’ve ever seen. Specs are awesome too. Just kind of a chore to go to the ford dealer. I live way out there.
