Really? The S&B filter I had on my Mustang with a K&N intake pipe would look like crud after just 6 months of use.

About 15 years ago I tried them. One in my wifes truck and one in a Honda quad. Evidence of dirt getting through in the quad was enough for me to go back to oiled foam on it. A couple of years ago I removed the one on the truck and replaced it with paper. The truck has 150K on it now and has not blown up. I think I only serviced the K&N once while it was in there. After I read in K&N's literature that the filter does a better job of filtering as it gets dirtier, I stretched out the interval.
1.) They may not be suitable for all applications / environments.
2.) People may be servicing them incorrectly and too frequently.

I still have 4 K&N pod filters, with outer wraps on my old Suzuki that have not been srviced since 2007 when they were new, but I don't ride it much.

I had a K&N filter long ago but ditched it for an AFE ProDry. I like that it's oil-free, requires nothing special and is reusable. All the cars that I have and my family's cars have all got ProDrys in them.

Going to go with one of them myself,Just to see if the filtering is any better than this K&N . Have to have the full airflow for forced induction but I also want the best protection .

I always used kn air filters in my dirt bikes years ago so I figured id give it a go in my veloster. Im sure it performed better then the oe filter from Hyundai but when I decided to clean it I did lo0k at it up to the light and said, wow that's a lot of daylight. I used it for 25,000 miles and last week replaced it with a napa gold air filter. Ps I did run my fingers down the pipe to maf but there wasn't any dust nor dirt so idk if I believe kn is all that bad. BuT everyone hear got me scared so I just changed it.

I'm surprised that there is no real competitor to K&N in the performance filter market. S&B kind of, but they only do filters fro a few select vehicles.

There was a couple of independent studies done and the K&N let in more dirt,, The best dry oem type filters tested were the ACDelco followed but the Baldwin..

Does the opinion of K&N change if you use one of their precharger wraps on the filter? Will that help improve the filtering efficiency?

I've had a cai on my dakota since '07 and the main reason I run a precharger on mine is I was sick of seeing all the bugs caught in the filter. IMO I doubt it filters any better other than keeping the really big stuff off the filter itself and cleaner looking. Plus I don't believe for most application a precharger is even available. I've had good luck with my mine but there's better filters for most cars/trucks. I do like K&N but I'm in the minority.

I want to like k&n, but as the saying around here goes, " why would you pour sand into your engine", anyways-
Thats why I dont like K&N. I have been using fram air filters and probably will try a purator next round. horse horse horse
I'll tell you what you do. Put a new paper air filter in, change the oil and oil filter and run the truck for a OCI then have a UOA done. Then install the K&N filter, change the oil and oil filter using the same exact brand/weight oil and brand/type oil filter as you used during the paper filter run. Run it for a OCI, then have another UOA done. See what the results tell you. Form your own opinion and either continue to run it or not. Simple as that. No debate needed. If the K&N sucks that bad, it will be immediately visible in the UOA.

Huh.

I've put a chunk of miles on K&N's between a 5.0, turbo Shadow, Avenger and our current Bonneville.

Generally speaking I run paper when possible now (Napa Golds, usually). Our SSEi came with an aftermarket Thrasher intake that has a K&N knock-off filter on it. Granted - it's been in use for some time. But it's still a "rock catcher".

Here's a 7,500 mile UOA:

Silicon below average.

*shrug* I won't blanket statement them and say your engine is going to blow up if you run one..

best air filters in the world in respect of filtering, load up capacity, flow, and lowest PSID.

Plus, they'll make any filter in any size for any application.

Guess which air filter EVERY F1 car on the grid uses?

OK, but pretty much every HD truck and piece of earthmoving equipment with a turbo, operating in the worst environments in the world run a Donaldson PowerCore wink

The PowerCore filters aren't small (or light) though, so they likely don't lend themselves to applications like F1 very well.

http://www.donaldson.com/en/engine/support/datalibrary/059806.pdf

They are 99.97% efficient and I would assume, given the applications they are used in (like mining equipment) also have a much higher particulate capacity as well.
