And FYI that DRY non oiled filter is suggested only for “non dusty environments “ by the manufacture afe.

I was going to go with one until I read that. It tends to be quite dusty where I wheel and I’d rather throw $20 at a paper 5 times in a hundred thousand miles than do any engine damage from a higher flowing (and less efficient at actually filtering) air filter.

After reading..... looking over the afe graph, showing dust holding capacity of their Pro DRY S offering, I can see why you opted not to go with one of those, considering you say you wheel in a very dusty environment..

From their website:

Comprised of multiple layers of synthetic media, the Pro DRY S offers excellent filtration efficiency and protection for street and light off-road driving conditions. Requiring no oils, it’s our easiest to maintain performance air filter

Notice the "light off-road".
as opposed to their top off the line (that requires oil).

Our Pro-GUARD 7 media was designed specifically for today’s rigorous off-road and diesel applications. Its patented hybrid design features both cotton gauze media and synthetic media, providing the greatest level of filtration efficiency and unparalleled engine protection and performance

I'm not saying I know which one would be better for anyone's application. But it does appear that the dry filter is not intended for lot's of off-road dust.

OEM..........$12. Most auto parts stores didn't have them in stock when I looked at NAPA and others. Was surprised the OEM was reasonably priced at the dealer.

Yeah I had one of the Pro DRY S in my old tuned BMW 335xi (which was an amazing car) and never had an issue with it. But that was a street only vehicle, unlike my JL.

The factory filters are cheap enough to not really worry about replacing as needed in my opinion. I’m all for a better flowing filter but I also tend to steer away from oiled filters these days.

I’ve had a brand new factory oiled K&N drop in filter cause all kinds of problems and take out a MAF sensor before (in another car) and I’ve steered away from oiled filters ever since. All the fancy electronics in newer vehicles do not like to be even lightly oil coated.

A good quality paper filter is all you and you engine will ever need. Paper filters usually have the highest filtering efficiency, dust holding capacity, and supplies more than enough air for the engine.

I personally stay away from other air filter media types (oiled and dry). The oiled elements allow oil and dust into your intake system. The dry media doesn't hold as much dust as mentioned earlier in this thread.

The only time I'd see a need for any other type of filter is if you're operating in a wet (like crossing a lot of streams, rivers, etc) environment. In that case, the paper filters will totally collapse once they get wet.

Yup, you can find for $12 but more often then not you end up

I do little if any offroading with my JL, but I do, do lots and lots of interstate driving though.

Thanks to all the diesel trucks on the road, etc., my air filter and cabin air filter get sooted up and dirty in a short time frame.

For me the afe Pro DRY S, air filter, has worked out well, cause I can clean as often as needed... ...with paper filers, I would be spending lots of $ replacing every few weeks...

Guess an owner needs to consider the environment and what works best for them.

I wonder if the fellow Jeepers clean up the paper filters from time to time?.. blow them with compressed air?.. would that damage them?

Thanks!

Paper OEM-style filters far and away filter better than any cloth filter, oiled or not. Air flow is a non-issue, as well, because there is tremendous filter area with the OEM-style filters.

If you run with a group and you are not the lead, you are taking some serious risk with the longevity of your engine running anything other than a good paper OEM-style filter.

For on-road, the cloth filters are fine. One nice thing is that you can run a cloth filter and then swap to paper for off-roading.

If anyone has any doubt, do a used oil analysis after running in a dusty environment with cloth and you will see a high number for insolubles.

I have run Car Quest house brand, STP, and Mopar, and they all look like they are exactly the same. I ran an off-brand from Amazon and it was similar but with a different color (black) rubber. But all my UOA's have shown a very low insoluble count, indicating good filter performance. Even after super dusty off-road trips out west.

I wouldn't. It can dislodge smaller particles that will wind up in your engine when you re-use it, at lest initially. New ones are cheap insurance. I run them 10k to 15k miles. Most are rated for 12k. I do go ahead and replace them after off-road trips with high dust, usually before the long highway drive home.

I just checked some prices: $26 or so for a Carquest from Advance Auto (15% discount), $20 for an STP at Autozone, and an AC Delco at O'Reilly for $21. Amazon has a Premium Guard for just under $18. It looks exactly like the Carquest.

Here's a deal. This one looks and feels EXACTLY like the OEM Mopar filter and is under $16 bucks.

OMIX Air Filter

I just ordered two of them. WIth 2 JLUR's with 3.6 engines, I like keeping at least two on hand for the next change. This deal is so good it bumps me to 4. The others are the Premium Guard filters that look/feel just like an AC Delco.

I live in the desert on a dirt road and our search team usually runs dirt roads in the mountains. I will stick to OEM.

Owners manual says

Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies considerably. Only high quality Mopar® filters should be used.

I haven't changed mine yet, how often do you change your filter?

I was living in Utah and changed at 10K and 20K when I got back to Texas and will probably go every 20K here.
