Hey guys.
Need your advice.
I'm getting an oil change special from AAP https://shop.advanceautoparts.com/o/oil-change-specials and need to select a filter.
I'm going to pass on Boss and that leaves me with Mobil1 vs K&N
Any feedback on how does K&n work on these gdis?
My buddy drives a focus st and he believes K&N is so good it even prevents a carbon buildup (no proofs from him tho lol)
Thx!
 
If it was between the M1 and K&N, I'd go with the M1. Both will work of course, I think the M1 is better.
 
You can't go wrong with either. The K&N has the advantage of having the nut on the end for easier removal.

Which can also be a source of oil leakage due to bad spot welds.

In rare cases? yes. But this really isn't a common occurrence.

True ... just sayin' it can happen. Efficiency is down on the K&Ns now if I recall past discussions correctly. Those two things about the K&N would make be pick the M1 if it was the only other option like the OP mentioned. Otherwise, flip a coin if those things don't matter to whoever's buying.

I agree on the final point. M1 would be my first choice too.

I usually go for M1 oil filters, but in my last oil change, I did not like the way it looked compared to previous ones. If you see one made in October-Nov 2018, I wouldn't put it on.

However, they are good.
 
If the choice was between those two, I'd take the M1 long before I would consider the K&N. Honestly though, I'd go for the Boss before either. It seems to be one Puro filter that's worth using.
 
there was a recent report about a torn adbv on PuroBoss, so I've decided not to run the risk.
I somehow don't like the M1, and it seems like K&N is not worth it, even tho it looks solid.
Sticking with my Fram FPS then

I heard the OEMs are designed for more flow. So in that case, I would get the K&N over the more restrictive Mobil-1.

Many here say higher efficiency/trapping is better. Well that depends on the application. Perfect example is my Colorado, which absolutely hates Fram Ultras. My Colorado filter is currently a K&N.

My Colorado doesn't like the OEM AC Delco PF61 anymore either. But flow improves when I use the Ecore version PF61E.

EVERYONE should find out more/correct info on their OEM filters first, before replacing them with either higher flow aftermarket filters, or higher trapping aftermarket filters.

I am not sure a tear is a big deal. The tiny amount of oil that gets past that tear will almost certainly hit the filter in a different area the next pass through the filter and be filtered. This is not like water passing through a house water filter where once its past the filter its used and never filtered again.

But given two identical filters I would choose the one without the tear. How many of these tears were caused by rough handling during cutting the filter open?
 
Considering that this was the reply i received from K&N on filter info. All they can say is it meets or exceeds OEM

Not being able to provide any useful info makes me wonder.

I like K&N as a company, mainly from the good customer service I have received from them. Every car in my driveway has a K&N air filter and I use their white oil filters from time to time with no worries. They are built very well, very strong cans. I have used one on the Optima, and in the position it's in on that car the nut works very well.
 
Triple_Se7en I wish I knew where to find the flow specs for Kia OEM filter.

Does that Colorado have a computer controlled variable flow oil pump? Sound to me like the oil pump is weak or being controlled in a manner that makes it weak and sensitive to the slightest flow restriction in the oiling system.
