To get more airflow you have to suffer something. I took them off my trucks years ago. Turned around and sold it on Ebay.

 

I do not mind using K and N's on my highway vehicles since they see little dust in that environment. Off road on my atv's is another situation though. Does'nt matter what the subject is, some people have their opinion and will never let the cold hard facts soak in. Ask yourself why a prefilter is even a purchase option with a K and N filter? It is certainly not a performance option.

 

Most people don't pour dirt on top of their filter in any REAL environment. Also don't remember reading what size of particles got through. Most smaller stuff just burns off anyway, otherwise we'd all have engine damage. No matter how good a filter is, it lets some dust in.

A K&N is made with cotton gauze. Cotton breaks down in water. You are only supposed to clean them like 25 times before disposal. The prefilter extends cleaning periods because it catches some of the dust. It is NOT to enhance the filtering capabilities of the K&N. You can take that straight from their site.

Don't know about riding in a fine dust but I can vouch K&N works just great in sand.

 

Duneaddict-As far as trying to SCARE people, I figure this is like the "use a condom" issue. It's best to press the point to hard, and have someone err on the side of being to safe. Then if there are those who want to ignore reality, well the consequences are their own fault.

What made me stop using K&N's a few years ago is that my filters were way to clean. A foam filter in that same desert dust would come home caked, yet the K&N was all nice and pretty. If the dirt wasn't on the filter, well then where did it go except into the intake???

In my mind it's just foolish to think that an Outerwears is going to make a big difference.

 

A dusty envoronment is same thing as pouring dust onto a filter....no doubt to the same degree, but dust is still in contact with the filter. If a prefilter extends cleaning periods, then how is it not enhanceing the filtering ability?? You agree it catches dust?? Later gents [img]i/expressions/face-icon-small-happy.gif[/img]

 

The stock box helps filter dirt too. Is it NEEDED to enhance the filtering process? No.

 

Lol....bottom line is the prefilter extends maintenance intervals for a K and N filter. You have already agreed it helps filter as well. THats the point I was making as well. Looks like we agree. [img]i/expressions/face-icon-small-happy.gif[/img]

 

I'm thinking that your opinion may not directly reflect reality. perhaps I'm just confused...
Did you actually notice dirt/debris inside your intake tube (after the filter)?

In my opinion, it's absolutely NOT foolish to think an Outerwear makes a difference, I've seen it time and time again.

Guess we'll just have to agree to disagree.

 

duneaddict,

"Horsepower: If it doesn't scare you, you don't have enough!"

great line, i must not have enough!! LOL

 

LoL!!! Yeah, I don't think I've ever had enough... is there such a thing???
I've always wanted to pilot a top fuel dragster or an F-16 to see if I could find enough.

It kinda goes along with that one song:

A girl too pretty, Too much money in your pocket, Too much whiskey (Well, I think I've found the threshold on that one)
