I just (as in an hour ago) installed the oil free AFE's. I like them and would suggest getting them.

Bought mine for $88 shipped (made an offer) from some company on eBay.

Compare their Pro5 (oiled cotton) to their Pro Dry and decide for yourself.

The K&N should perform as well as the oiled cotton AFE...

From what I was able to find, when measured the same way (same vacuum) they flowed about the same but the oil free did a little bit better in terms of filtration and didn't require re-oiling of course.

^^^ truthfully, its an exercise in hairsplitting, but I've personally seen more documented evidence of oiled filters flowing marginally better than dry ones (other folks on here have argued the other way...).

Still, both outperform the paper, so you really can't go wrong.

flip a coin, its just that simple.

I don't know about AFE dry vs K&N oiled (although they claim their oiled performs better than their dry), but I always found this old graph AEM used to post very interesting.

Basically it shows that K&N filters flow the best unitl they are litterally caked with dirt (where it drops off is like a measuring cup of dirt!), afterwhich the AEM dryflow performs better.

I don't think AEM has this on their site anymore... still, it shows that K&N is a pretty good filter (best clean flow of the lot!)

Hmm... Actually, the AFE pro dry (and one other -- is that the oiled one?) is on there... neither of them doing too well either...

Again, these results are from AEM, and considering their filter isn't even shown to offer the best flow when clean (which is probably why they pulled it -- bad adverstising!), my guess is that it's reasonably reliable and objective info to use in deciding on an airfilter.

Actually, they all flow about the same until you hit 20 grams of dirt.

That's a lot of dirt!

Just keep your filter clean and it will flow just fine and the dry ones do filter better if you are to believe AFE.

That's an incredibly good point!

So... yep... back to the exercise in hairsplitting

6spd · 03-25-2011, 03:27 PM

right on, it'd take a long time or a lot of dirt roads to collect 20 grams of dirt.
