What do you guys think about those aftermarket style air filters out there, worth the extra money? Why?

 

[lornix]

Are you talking about the cone-shaped style? I can't speak for those, but I run the K&N air filter - the square one with the oil that you can clean and reuse, and yes, it made a difference. Engine runs a little smoother and seems a bit peppier.

Ya I am referring to the drop in K&N re-usable filters.

i ran a K&N drop in and it coated my throttle body in dust in less than 6 months. i switched back to paper and threw the K&N in my stepdad's DD 96 XJ. i didnt notice a difference going back and i have quite a few bolt-ons.

and yes, it was oiled properly.

same here. got it all dusty during the dry summer months. I run regular paper filter now. filters better.

I have heard reports from others with very similar results to the ones you describe which is why I have never ran one.

A K&N filter flows well, it does not filter well. Throwing a sock (not an actual sock) over it can help somewhat with the lack of filtration. There's lots of SOAP (spectrometric oil analysis program) results out there showing how big of a jump in silicon contamination a K&N causes over a paper filter.

We run K&Ns (AFS) on the helicopters (really big ones) simply because they filter much better than what was there before (chicken wire, basically) but cause very little restriction in airflow. When they get dirty, they restrict much more and engine performance will suffer noticably. But we can clean them, which is better than other filters which would need replacing (which could be logisitcally impossible).

AEM makes a dry cleanable filter that flows better than a paper element, and probably is on par (or better) than the K&N. They might not make a drop-in replacement though.

drop in, AmsOil, great I really recommend it..

Elaborate on the sock part, what exactly are you talking about?

I think he is talking about this:http://www.knfilters.com/wraps.htm

I guess those were popular before my time.

Lots of people still run them, and you can get better ones than the K&N.


Although, the reality is you see less and less K&N filters out there.

 

[xjjeepthing]

I run K&N stuff in all my vehicles. I like them feel they make a difference. I have never had a problemn with one.

x2. But I also run a FRAM oil filter. GOOD HEAVENS!

 

[Kyle]

IDK I just cant see spending all that much for a filter when I can get a paper one for 3$ and keep a spare.

True, but you could spend a little more and never have to worry about buying another one. Ever. :dunno:

But the dust issue, cant be good for water intake either.

 

[TrueBlueXJ]

I would think the oil helps catch a lot of dust (hence the filter getting dirty and needing cleaned) and it's not gonna let any more water in than a regular paper filter I wouldn't think.

But to each his own. I run one; never had any problems, only improvements. The top side of my air box is always clean as a whistle.

IDK Maybe I will give one a try, we will see when I get to the parts store.

Kyle,Just buy the filter and build your own intake tube and it will be half the price of a K&N kit!
