If you over- oil or under-maintain them then yes, absolutely. I'm not a fan of oiled filters on any element type mass air setup, but the trap door mass air on the 22re isn't really bothered by an oiled filter.
JMHO, YMMV.

I ran one for about a month. a couple days of wheeling down some dusty dirt trails, and they were nothing more than metal screens with a bunch of mud in them...
they're too much of a hassle, and I don't think their gains are worth the troubles they can and will cause down the road. I went back to a stock paper filter and never looked back

I think it depends where you live and the type of wheeling you do ( if you do)
Hamper gas mileage? Yes. Potentially. If you live in a very moist/wet or very dusty area, then they will let more particles into your engine and can clog certain elements of the engine, causing problems. Or let water past.
Personally, I have used a K&N in both my '93 single cab (AT LEAST 80K miles) and in my '95 4runner (about 15K miles) and havent had any problems. But I live in a cold, dry place I actually could tell a difference between the stock paper filters and the K&N. My '95 actually ran better :\
Off-roading, though, I always switched back to the $15 paper filters. Too much mud and gunk flying around.

Stick with the stock paper filter if you plan on wheeling it. If your just looking to get it just for gas mileage there are other things that will help you more for the money. Such as a tuneup, new O2 sensor, cat and other stuff

So called "Cold Air" intakes & the associated crappy filters are one of the worst things you can do to the long-term health of your engine. Stick with OEM intakes & filters & you'll pull MUCH MUCH MUCH less dirt/filth into your engine.

I ran my '93 22R-E for ten years with a K&N and put over 100,000 miles on it. It paid for itself, because I only bought one $10 cleaning kit and it lasted quite a while. I definitely rode that truck hard and had it in deep mud many times. I was very satisfied with it and I never had a problem. However, if you were to contaminate your paper filter, you have to trash it and buy a new one. The K&N one is very easy to clean and reoil, although you need to let it dry. Normally, I'd do it at the end of the night; and it'd be ready the next morning.

I've been running K&N filters in both my rigs since June. I noticed a huge gain in HP in my Durango. A little less MPG (for obvious reasons) but only 1-2 mpg on the freeway
Didn't notice any change in my Yota. At 5,000 feet and almost 18 years old, it runs like a turd no matter what. I did notice a tiny increase in performance back in September when I ditched my 265/75s for some lighter 245/75s and emptied my tool box. Bottom line for me is: $20 for each throw away filter vs $60 for a K&N. It pays for itself in just a few months.

I'd like to get the whole cold air intake set up for my Durango (street driver)
But there's no way I would go with it in my truck. I've seen a new Dodge Ram with one and a ruined engine when they got it a little too wet.
