I was wondering if anyone has tryed a K&N style filter that is oiled and also tryed a dry flow filter like an AEM or fujita ? Did you notice a difference in performance from either. Also I've heard some people have MAF issues with K&N style filters is this only a problem if they over oil them? And last question is does the brand of the filter make any difference for example K&N and spectre are both oiled style air filters and AEM or a cheap e-bay dry flow.

I'm pretty sure the CRABs system uses a K&N filter and that's what I roll with. I don't know about it being oiled but it has never caused my engine to throw a code.

I would never use a spectre and yes it does make a difference. I used to have a grand am with a dry cheap air filter and it never ran right, like I always say if you're gonna do something, go all out, K&N man...

If the filter is over-oiled it will mess with your MAF, and I believe some throttle body cleaning fluid will fix that if you have that issue.

Personally, I think the fact that K&N-style oil-adsorption filters were the only ones that were able to take volcano ash during the St. Helens eruption without a retrofit says a lot.

CRABS to come with a K&N filter..FYI

Here is all I gotta say... When your dealing with something like an engine... Go with the industry standard because they know what they are doing more then anyone!! And K&N is by far the industry standard!! But don't worry about the Oil, it isn't like it is dripping with oil, it is actually barely damp!! I had a drop in K&N in my cougar an never had any issues!! It even made for a little more aggressive exhaust tone!!

K&N make very good filters.

AEM have some nice paper ones as well but they wont last
like the K&N cause you cant clean & recharge (re-oil) them.

Sometimes the K&N whistle and some people dont like that.

I love my K&N and would never go with anything else. The only possible bad thing it may be doing is that every once in a while when I go to get gas and have less than 1/4 tank then I fill up it, when I go to start it up I can hear my CAI suck a ton of air and my car won't start on the first try or it will but studder so I have to give it some gas. It starts after the failed start but you can hear the intake suck the air up and I think it just leans the engine out.

I have an AEM dryflow filter and love it. I agree that you don't cheap out on filters. I like the easy of cleaning for my dryflow and don't feel like spending $50 on a new one anytime soon.

Both are good filters (AEM vs K&N). Its all based on preference.

Most people on here probably have CRABS and therefore have a K&N. I like, others don't. I know there is a pretty massive debate over on the Bob is the oil guy (BITOG) forums if you care to look into it. Overall I feel that it is personal choice, and you can't go wrong with oiled or dry as long as you get a quality filter.

If you do go with something other than K&N let us know what you think!

Im running the APC dry filter you can get from Pep Boys. I had a little issue awhile back with K&N. Im guessing one time I recharged it and I over oiled it (which I didnt think I did). I followed the instructions but some how the oil destroyed my MAF. $310 part I dont want to screw up again. so Im sticking with dry filters

For reference, I spent a ot of time wasted reading the Oil Adsorption vs. Dry filter debate.

This is pure opinion, but hear me out:

Yes, over-oiling can damage the MAF, but only if you over-oil. Also, MAF cleaner will fix the MAF assuming it's caught early enough.

My last car did not use a MAF, but it seems to me that the most prudent course of action is as follows:

Buy a spare paper filter fo use when cleaning/oiling your K&N or other Oil Adsportion filter.
Don't over-oil. Always let the filter st and self-wick for 24 hours.
If you do get an over-oiled filter, or if you over-oil it, let it sit for longer with some kind of absorbing media to suck out any ecess oil from the rubber frame and the pleats (paper towels work). Change often or when they get saturated.
Go light on the throttle after you install.
A week after you install the filter would be a good time to use some MAF cleaner and clean your MAF. Even if the MAF doesn't need it...it sure as hell can't hurt.
