1) "Efficient" as in a straight delivery method to the intake. No grooves or recesses like the factory air box which isn't exactly an aerodynamic channel for the air flow.

2) While that link is very informative, Be it that they were testing filters intended for diesel engines, It was written in Sept. 2004, So from then until now there might of and/or probably have been improvements since then in filtration with the different brands. Though I can see your point where Performance = Lack of Filtration for some if not most of the brands.

3) I'm not necessarily aiming for the "cold air" part of the deal, If it gets a little extra HP combined with the sound I'm sure most owner's can appreciate, then for me it's a win-win situation.

1) I have no comments about the stock intake in terms of flow restrictions or turbulence. Keep in mind that smooth does not always mean better flowing.

2) Diesel or gasoline, the filter media is the same. Yes it was written in 2004, and nothing has really changed. No leaps and bounds in filter technology since then, you can take the data as a reasonable way to compare different filter media. Draw your own conclusions, you will see k&n is not the worst in all regards, but if you could figure a way to weight a score in each category to do an overall comparison you would see it ranks in the lowest couple.

3) Where you are going to pick up the HP gain in k&n is related to the higher flow rate of the filter media - which also directly translates to filtration properties. k&n filters let through more air....and more particulate matter.

If you wanted to find the best of all worlds you could get any intake kit you wanted, and then find a better filtration media from another manufacturer, it is possible to keep filtration while flowing more, and surface area plays a large part into that.

1) That may be true, But I would like to think that the less resistance the air has to it's destination the better.

2) Obviously there hasn't been in leaps and bounds in the innovation department of filters in the past decade, I don't think that was mentioned anywhere, But some companies are good about further developing their products. Looking at all the graphs presented, you can obviously tell just by K&N being featured in the lowest group of all the manufacturers mentioned that their products would be ranked in the lowest group of performance out of all the brands listed.

3) Again I don't think this one was debated. If they're aiming for pure performance results then you should expect the area of filtration to be lacking. That boost in performance doesn't come at the expense of nothing.

4) I would like to stick with the K&N kit, But what would be a good manufacturer to go with for the filter aspect?

Re: Can you wash/reuse the stock air filter in the I6 Air Box Assembly?

Amsiol comes to mind as the obvious replacement for the K&N filter:
http://www.amsoil.com/a/nanofiber-synthetic-air-filter
(second option down are generic replacements for other kits and intakes)

There are other manufacturers of cone filters, I think the K&N filter is a 4" base, so you could start searching from there. You'll also note that the amsoil filter performs better than the K&N, but the tests indicate that the K&N filter needs to be treated as a filter with a shorter service interval, it seems to become more restrictive faster than other filters(which also partially means it filters better, among a bunch of other properties).

I'm not an amsoil fanboy like some people are, so I am not trying to push their product of K&N because I am about to link you to a website where you can buy it right now, I'm just trying to point out that there are other alternatives that may be better for your engines health.

1) Alright man cool, and don't worry, I didn't take it as a fan boy gesture lol, If you've got a brand you prefer and have had good experience with it I want to hear it lol.

2) Does the second option down include the same filtration technology as the first part mentioned?

Re: Can you wash/reuse the stock air filter in the I6 Air Box Assembly?

Another option is to get the pre-filter like I have on mine...my actual filter rarely gets dirty...I just take off the pre-filter, clean it, and put it back on. It's like lace panties for your air filter...ahahhaha. It also keeps water out of filter media. Cheap insurance, and it looks nice.

I don't know of any tests, but this might improve the filtration of the K&N filter enough to maybe equal that of an Amsoil?

Lastly, I've sent out for oil analysis on a few occassions with my last 2 Jeeps, and once with this one. Never any mention of high contamination...and that is a criteria they look for.

Linky for filter panties....

Yes.

They also sell filter "pantyhose" covers that go over main filter.

Re: Can you wash/reuse the stock air filter in the I6 Air Box Assembly?

Putting your money into aftermarket exhaust system is probably the best way to go significantly improving engine performance and it does this through means of two main principles:
1. By reducing the exhaust back pressure engine power is increased,and
2. By reducing the amount of heat from the exhaust under the hood. This reduces engine compartment temperature and consequently lowers the intake manifold temperature, increasing power.
