A lot of people tend to run the K&N Performance Air Filter (http://www.europaparts.com/kn-performance-air-filter-33-2209.html)

I have the K&N. Wish I wouldve gone with AFE. I have it in the B6. Its better for a piece of mind with the AFE.

Run the K&N drop in... Clean off your MAF every now and then and call it a day. I clean my MAF every oil change

I run the AFE. Nice, cleanable dry filter. Just pulled it and cleaned it (ran a hose through it) as regular maintenance. I went with it over the K&N because it's slightly less maintenance for something that provides relatively little value.

I have the itg filter got it from AWE, it works fine for me. If you do get it dab off the extra "goo" on the foam filter I had to clean my maf after I put it in but no issues since then.

I put in my AFE Pro dryS 5k miles ago, no problems. Peace of mind not to have to worry about the MAF sensor getting saturated with oil. And I hear the turbo spool better which is kinda nice.

drop in high flow filters improve flow by reducing filtration. even then, benefits will be almost nothing. its a popular mod around here, but i would suggest rethinking it unless you are ok with letting more crap into your motor.

i have an itg filter from eurosportacc.com

its cool cuz u never have to reoil it

They should help in theory but I didnt notice any difference on my stock motor, after chip might be a different story. The people who fuck up there MAFs are people who soak them with oil when they clean them but they only need to be cleaned after like 50k miles.

I'm running the K&N also. I didn't really notice any performance change either but I'm sure that it flows more air into the engine. Ed Gein is right, if you're careful oiling the filter you shouldn't have any MAF issues

I wouldn't run a K&N filter if they paid me to do it. It's not like I've done any testing on them or anything...

I dont get the whole deal that you have to oil the k and n ? Never did it never will.

When i installed the RAI TP/DP combo i drove it around with the stock filter to see if i noticed anything... got back and dropped in the AFE prodry and the sound was much more noticeable, the turbo seemed to spool up a tad bit sooner.

I usually don't either, After the first time I clean the one I bought I probably won't oil it again. I haven't oiled mine on my last 3 cars and haven't had any issues.

What are some of the benefits of the AFE Filters, also which one are people using, oiled or non-oiled? I've always used K&N on all of my cars, and never had a issue with my MAF sensor...even after it was re-oiled. I'm up for trying the AFE though, and anything that helps my engine breathe better is always a plus! Especially since I'm up to about 500 miles a week plus, and I just hit 190k miles on my DD! [up]

they make it high flowing by using material which is more porous than stock. the oil is to compensate some of the filtering ability lost (we can all agree that dirt and debris likes to stick to oil).

I have a carbonio CAI, and despite how it doesn't add any performance, damn it sounds cool. I get comments on it all the time. Really lets you hear turbo spooling and diverter valve. Here is a video of mine:

I know you are just looking for drop in, but when I compared my factory air box to carbonio, its obvious why it's a good choice. The turbo gets so hot right next to the plastic air intake, and the carbonio has thick metal shields.

$45 filter >>>>>>>>>>>>>Carbonio.

I wouldnt pay 400+ because it "sounds cool". Thats probably one of the mods that is the biggest waist of money for our A4's.....

Yeah I had a carbino on my B5 A4 it looked cool w/ the CF engine cover I had as well(sold both of them within a year) but I am not a car show kind of guy really so could care less.. as long as its low and has rims thats all good.

On my truck I traded in on the audi I had a full afe intake w/ pro dry and that was on a diesel (542hp/1086ft lbs) and it worked quite well... thinking i might try the AFE pro dry dropin on my car now...

I agree, that's why I got this for less than $100 (custom built)

I have been using the AFE pro-dry for about a year now without any problems. I bought it because it is a re-usable filter and I can get a longer use out of it for the money than re-purchasing new stock filters.

all you need is a cone filter(i got K&N) for $40, 2 x 90 degrees pipes, silicone connectors and hose clamps from silicone intakes dot com and you're done. Less than $100. I have the setup mr shickadance has, I couldn't find his post so here is mine and another one I found.

I feel like that has to do help the car breathe better than anything else on the market.

i think you can say the same thing about any reusable high flow filter. i don't understand why people think its a good idea to reduce filtration, and then use the same crappy filter over and over again as if that doesn't make the already avoidable issue any worse. its not like filters are cost prohibitive or need to be changed all that often. it would be one thing if this sort of thing significantly increased flow, but it doesn't. the payoff is sound at the likely cost of motor longevity...awful.

Not trying to flame but do you have any solid evidence of engine failures on our cars that can be directly attributed to reduced filtration?? I would be curious.

it is one of those things where it would probably be fine, but then one day a small piece of this or that gets in between a valve and head, or blades and turbo housing. Also, the more dust, the more scraping on cyl walls (never had proof but heard it a lot), and then of course, if dust is getting into valves and what not, it can damage them.

@CorneliusRox: Thanks, this is a good way of looking at it.

Unless you are finding the debris actually inside your motor, there isn't going to be an easy way to make a realistic direct cause effect statement between a motor failure and a crappy filter (as far as I know). The more crap you let into your motor, the more crap you let into your motor. The air filter is there for a reason, that being to filter things OUT to prevent damage and unnecessarily increased wear (wear being something that is cumulative).

It would be one thing if air filtration were reduced on a motor that saw more frequent rebuilds. However, we are talking about what are mostly street cars that will likely never see a new motor. Personally, given that, there's no way I'd willingly and knowingly do something that would cause any internal motor issues or compromise the longevity of the motor in any way without significant and measurable benefit, which you will NOT see with a drop in filter of all things.

honestly, you seem like one of those people that likes to knock things without real proof. Im sure the flow isnt that much that it is in any way dangerous or reputable companies would not sell them! A lot of us are trying to make more power. whether thats a chip, or a new turbo...more air flow is going to help. So unless you have proof that the "high flow" filters are dangerous...please quit your preechin. i ran a k&n filter for about 3 years/70kmiles on my b6, ran into an issue where it wasnt running right, and when we pressure tested the cylinders they were nearly perfect for its age (besides the one where the head was cracked).

you are assuming i said at least a few things i didn't say.

your assumption that something being on the market meaning its safe is extremely naive as well. They are on the market because people buy them, thats all.

good luck with your drop in. :rolleyes:

We've already had luck with them, Thanks though.

your assumption that something being sold by a certain company meaning its safe (or not harmful) is nothing less than extremely naive. k&n sells them because people buy them, thats all. given their advertised gains, im sure they are totally up front about everything... right.

good luck with your drop in and all that extra power it has freed up. :rolleyes:

ps. i have some reusable high flow tampons you might be interested in.

Hmm, so what exactly am i assuming you said? i mean, i quote what you said...you said it...

you need to stop over analyzing things and stop being such a pesimist. Take a minute to learn what youre talking about before you start preeching things. thats all im saying. If these filter companys made products that harmed peoples engines and cars, they wouldnt be in business due to lawsuits.

Honestly though, you would make a great parts guy at the dealership. Youre exactly what they want. Trust me, i know...

i don't recall saying anything about.drop ins being "dangerous" or anything similar. but alas, youre right, ive seen the light. your moving story of a whopping 60k miles running a garbage drop in before cracking a head has shown me the error of my ways. :rolleyes: k&n rulez!!1! i heard that if you rub their filter oil on your junk, then all of your children will be baldwin brothers.

regardless of filter choice...if anyone is looking for something a little more substantial (than meaningless anecdotes) bobistheoilguy has a good comparison of different types of filter media.
