i love me some AEM dry flow, those things are beasts, run some water into it and clean it up every 3000-5000 miles, shake it out let it air dry a bit and throw it on... screw all that oiling crap, too bad aem doesn't make a lunchbox

Do they make for GS500???

Yeah, oiling is a PITA....

But everything is a compromise......I think that K&N get the combinationo of good flow and good filtering by using oil......it allows fairly big passage ways for air to pass, while the dirt particles "stick" to the sticky oil........

AEM look like real quality construction though.....

I look for two things in filters...quality construction and ease of use (like being cleanable and reusable)..

Just remember the point where you are getting the reading in this case (the air box). So your rolling along at 6000 Rpm with no load, you WFO the throttle but your still doing 6000 Rpm, the vacuum (remember we are doing a filter test in this thread)  in the air box will remain the same because the RPM still has not increased.
EDIT: Granted you would need a gauge sensitive enough to measure the minute reading you would be getting in negative pressure.

another interesting video....of course one sided..but some good points.....

More flow = less filtering
More filtering = less flow

Which is more important???

Many say filtering is more important....You install a filter to...well, filter....

The "restriction" of a good filtering filter is insignificant in "normal"use...

Here is the K&N filter demo gizmo I saw at the auto store....

Impressive demo.....if you think that lifting a ping pong ball has anything to do with running an internal combustion engine........

In the real world, I don't think K&N makes any difference..

The K&N dispute has been going on long before I started wrenching professionally back in the early 70's. There will always be people that chime in and tell you about 200, 300, 400 thousand trouble free miles, and I have no reason to doubt them.
Personally I think they flow more by filtering less? Here is a photo I took of one of mine...it actually had holes that light shined though.

Yep...flow more filter less.....

There is always a trade off...each manufacturer points up their strong points and plays down the weak points.........K&N stresses less restriction....true...but does it really do anything for you??

The other guy stresses better filtering....OK true again...but how good of filtering do you really need to make a difference?

I mean does more filtering give you 20 more miles to the life of your bike, or 2000 more miles to the life of your bike?  Or 100,000 more miles??  Or will something else do your bike in well before it wears out due to dirt entering thru the filter??
