 Subject: Evil cotton gauze air filters!
IP: Logged
Message:
Welp, a couple weekends ago I had taken apart my throttle body and it was downright nasty. I cleaned it up (including the IAC), and I was able to correct a idling issue by doing so. Well, like clockwork, the idling issue came back this morning. I took the whole TB apart again and there was an oily, gritty film in the TB air channel and the IAC channel.
I cleaned it all again, and this time I took out the air intake to replace it with the stock setup. I may not have the extra *umphf* and mileage, but hopefully I won't have to deal with a cruddy TB and IAC anymore. Until I can find a foam or Amsoil air filter I can fit on my aftermarket intake, I'm not going to put it back on. The Airaid filter I had was a standard "oval cone" style with a 13" circumference air channel / 4" diameter. If anyone knows where I can get a non-cotton gauze replacement, please let me know. Thanks!
Kids, say NO to cotton gauze air filters (K&N, Airaid, etc).. your vehicle will thank you. And to you all you people out there who have preached how much cotton gauze air filters suck.. well.. point taken.

Check your intake tube(s), and wipe your finger around the intake manifold inlet - you'll have to remove the TB again to get good access. If you find the same residue there, you can bet it's all over inside the intake manifold as well.

dumped my K&N last summer. Talk about garbage. I put the stock one back on. Runs the same and same MPG. I'll never put another one on any of my autos. all there good for is racers that only care about winning at any cost. Most of them do a rebuild after a few races anyway so why worry

I know the resonator had some in it. Not sure about after the throttle body, but I'd imagine there would be. I'm probably going to have to get some Seafoam or that AutoRX to pour down the intake. Only way I know to really clean the air intake after the throttle body. Sucks that I have to do it, but it is by screwing up that we ever learn anything in life. LOL

Oh wise OBIO3, your words speak true. LOL First the spark plugs, now this. ;) Well, I'd like to find a foam filter to go on the intake if anything so I don't feel like I wasted my money on it. Eh, may just eBay it and go with a foam drop-in. The cotton gauze filter probably wouldn't be so bad if I didn't live in such a dusty area of the country.

For those of you with the 4.7L, here's something to consider before spraying stuff into your intake.
Think of your intake manifold as a large cylinder laying down with the in-hole at the rear. It is, there's just an extension that wraps around to the top where the throttle body is.
The manifold outlets are on the sides of the manifold, but it's not that simple.
Each intake runner makes a complete 360 degree loop inside the manifold. Each runner opening is roughly half way up on the inside of the manifold, and the open end is pointed UP. That means the lower portion of the inside of that intake manifold is one big catch basin, where liquids can accumulate and fishies can swim about.
What you may find collecting there is all that yellowish emulsified oil that gets through the PCV valve from the oil filler tube, and a lot of the dirt that re-usable filters pass because of the big holes in that gause mesh (well, the dirt that didn't get sucked into your engine, anyway).
Spraying stuff into that intake system may cause more nasties to just pool inside the manifold and slosh about.
Just my $.02

You might call Amsoil and ask if they'll make a custom filter; if they don't have something in stock to help.

jp and others, I am in the same place you guys are in. well maybe. i went off of some advice tip to gain mileage using K&N air filter. changed my mind after reading a post about oiling your filters and where the oil will end up. thought about it and figured it wasn't worth it. now considering cleaning with seafoam down the throttle body or vacuum lines. Is there any reason not to do it, or to be cautious about?
I've seen this done on carburetors but not on throttle bodies, much less vacuum lines. Not too sure what to expect. Any feed back would be great if you guys have any trouble. Thanks.

DanK ..... I'm with you and your wisdom. I'd like to add a bit to the wise advice you passed here. those filters not only pass dirt but really fine sand. And in my opinion I believe they pass a bunch. Also think that sand/dirt and mice are from one end of the engine to the other. Has to be. I think sea foam and auto rx and any other cleaners you can think of is the last thing you want to do. Yes it may well bust some of it lose but none!!!!!And I mean NONE of these cleaners will desolve sand and most likely not dirt. My feeling is your going to set this garbage to moving to places you do not want it meaning worse then the problem it's causing already. My engine is the 5.2 . In all my reserch and hoping I am correct, I think the 5.2 passed the garbage to it's grave but also think it took a tole on my motor doing it. I'm so so happy I do not have the 4.7 with this situation.Forget the foam rubber covers. Poor some dust on one and give it the air hose for just a couple of seconds. check both sides and at this time your allowed to get sick to the tummy.

auto rx is only to be added to your oil. not to be poured down your intake. you that and might have more trouble than yo uwill expect.

Sounds almost like a danged if I do, danged if I don't situation. Hehe
Well, it is a gamble using Seafoam I suppose. It could either do one of two things, cause it to break up and be sent out the exhaust w/out a problem or, as DanK said, it gets caught in a place where I don't it. Suppose I could take apart the manifold, but that is a lot of work, and I'm not too sure I'm up for it. I'd hate to see how nasty people's intakes are that have had one of those cotton filters in for an extended amount of time.
Yeah, you are correct, Jecht. AutoRX is only for oil. My bad.
Hmm.. oh well, guess I may just see how it runs after a few weeks and go from there. No need in messing anything up if I don't have to. :)

Anything stuck is going to be in the intake. The rest went through the intake valves and either burned up or passed through the exhaust valves. In a nice tight engine I'm going to assume nothing or pretty much nothing got past the rings. If it did it either settled in the bottom of the pan or went to the oil filter so bottom should be just fine for sure I would say. Your most likely just fine. My only concern is the sea foam gamble. Either way, with or without it's a gamble. Still glad it's not me

I do notice a power gain with a K@N airfilter. People fail to realize that YOU HAVE TO FRIGGIN OIL THE FILTER IF IT GETS DRY!!!! It dry's out over time and NO, if you use the right filter oil, it will not crud your intake up. Use the K@N recharge kit and you will have no probs. I have never had a prob with buildup with a K@N filter. Gotta remember, the cotton really doesnt stop the micro particles, the oil does, so unless you want an ineffective filter, you have to oil them. But yes, I do understand the concerns some people have about them.

Uhh, Chris, this thing is 3 months old with less than 3000 miles on it. It is practically new. Check your throttle body. I bet you have a nice layer of oily shat in it (take it apart, don't just stick your finger in it). Or worse yet, a nice thick layer of hardened black carbon. We aren't just talking about the grit passing through the filter, Chris, we are talking about the oil passing from the filter as well into the engine.
I've ran K&N filters on virtually all my vehicles and they all eventually exhibited one engine problem or another (usually involving acceleration). It is just this time I was squirrely enough to take it apart and find out just what the problem was with it. I've always followed the recommended service procedure on the filters. Yeah, fool me once, shame on you (K&N, Airaid).. fool me twice, shame on me.. fool me more than that, I'm a mook! Next time I will put two and two together and realize what is going on. LOL
Frankly, I'd rather just go back to a paper filter or foam because it is better than having to take it apart every few weeks to clean it.Would hate to have something worse happen to the truck or even the IAC motor crap out. I can tell the 4.7L is a bit more sensitive in more than one way.

I just did a throttle body clean. I took the throttle body off and you can see down into the intake manifold. It had a little black, but was EASILY washed away by carb/fuel injection cleaner. Gave me a lot more power too after doing so. I used 2 cans.

Yeap, but you also have to take in quite a few environmental variables. I live in a very dusty area of the country and have to travel a lot of backroads. Hence why I had to take the TB off again and clean it in roughly 3 weeks. Granted, it wasn't as bad as before, but it was noticable. I'd imagine that you'd hardly ever have a problem if you spent all your time on-road.
Annnd I have no idea why it double posted earlier. Eh, oh well. Must of double clicked on accident.

Chris G. ....With all due respect..... Guess you figure we can't read instructions. The K&N filter comes with the proper amount of oil in it already and the instructions say DO NOT OIL FILTER WHEN NEW. IT COMES TO YOU WITH THE PROPER AMOUNT OF OIL ALREADY IN IT. The instructions also say DO NOT OVER OIL FILTER . although I discarded my K&N I do still have the cleaning eliments and the oil THEY SELL to complement the filter. The instructions go on to say once you oil the filter at cleaning time that's it. DO NOT REOIL UNLESS CLEANING. It also states the oil is designed not To run off or out of the filter. This is the K&N filter company instruction. Reading your post I have to assume you disagree. The instructions also state to add more oil other then inital oiling will plug the filters breathing ability. Every test I have read on these filters states the filter does a terrible filtering job untill it is practically pluged with dirt. I do not know anybody with the gute to run a filter this dirty. Oh, K&N being the exception although they do state to run it dirty fof best filter results. Hmmmmmmmm.... That tell you anything?????

Who is your question directed towards, Super bee? The Airaid intake I had was less than 3 months old and had less than 3k miles. On all my other K&N branded filters I've owned, I was always sure to service them every 3000 to 5000 miles using the cleaning spray and oil (was sure not to over oil as well). Usually at every oil change since I had the hood up.
