I have been hearing different info about the high flow air filters. Some people are saying the dry flow are better and some are saying the oiled are better. I have heard the oiled cause your IAT sensors to fail and clog up the throttle body. Has this happened to anyone? I just put in the K&N filter(oiled) and want to make sure I am not going to do any damage.

 

I guess the dry filter will filter out particles a tad better than the cotton gauze oiled filters. But they don't flow air nearly as well as the oiled ones. Especially when they're alittle dirty. Got this info from someone that works with both types for a living.

 

Never had any issues with the MAF sensors in my mustangs or the IATs in the 3 rams I've had.

 

yeah, if oiled k&n filters were doing all this damage to cars. they would have been out of business years ago. you just "hear" these stories. i have never met anyone with problems due to the k&n filter.. i personally have one vehicle with over 100k miles on the same k&n filter with no problems.....

 

Have a read of this:

http://www.bobistheoilguy.cohttp://www.bobistheoilguy.com/cms/in...d=58&Itemid=66 for some test data on various types of air filters.

 

Meh, you can read about which one is better until you are blue in the face, but IMO, they are all just about equal. Some claim that K&N filters don't filter as well as a paper or dry flow, but let me run something by you: Look at a K&N filter and then let yourself realize that what little particles get past that filter would instantly be incinerated in the cylinder by the heat. You wouldn't see any scratching or anything like that, but let the people believe what they want and use what you want to use.

 

you would think so. i have a bud who put a k&n on his yamaha atv for 1 day and now it smokes like a ****! gotta tear it down and replace the rings, oil ring at the least.

 

Silica(sand) doesn't incinerate inside an engine. It just doesn't get that hot in there. But it does make a fine grinding compound.

 

That's nice, but on average, a sand particle is about .05mm-2mm (50-2,000 Microns) in size.

What is a K&N filter rated at?????

Let's see....


So if you look real close, on average, the majority of FINE air containment is 1-5 Microns in size and an oiled filter is capable of stopping that. Sure, if you're going out to the dunes or something like that, then paper is the only way to go, but don't think that an oiled filter is junk because of what some people have to say about them.

Same to you...dont think dry filters are junk just because of what some people have to say about them. No one here has made a single comment about one type being junk. Yes if you are going to be in the dunes alot then a paper filter would be best but for about 98% of the people who are buying them, either oiled or dry will work perfectly.
