The DNA stage II filter provides the greatest performance gain per �/�.

For buddhist riders:

try this

Yes you will feel a difference with the DNA filters, if money is short at least fit a stage 2 filter.

you have to try and you will feel the real difference :)

I may be a bit late in posting in this thread, but I just got an xt660z so bear with me.

Public holiday today so I was tinkering with the bike just looking around to see if I could find this airbox. Pictures in the first post are gone, but Kev's link with an explanation had some. My airbox doesn't look the same at all :tard:

Removing the side cover on both sides I am presented with a cone-looking air filter sticking up in the middle. Am I right in assuming that I could theoretically remove one or both side covers and get the same, or better, result as removing the snorkle and/or drilling holes in the sides? The way I see it all the air would pass through the filter in the middle and no air would bypass it. I understand that going for a ride on a rainy day or washing the bike would not be a good idea with the side covers off, though.

DO NOT DO THIS.

the airbox setup on the Tenere is very different to the R & X's. When you remove the side panels on the Tenere, you are in the CLEAN AIR SIDE of the airbox.

You need to refit the side panels, but, as you have it apart - grease the edges a little to get a better seal (some do leak air/dirt).

Look at my sig line to get to the modifications index,

The snorkle on the Tenere is under the seat, held in place with 4 screws.

Wow really? Hmm... There was no grease on the edges when I had a look, and it's only a couple of weeks old. Also, the snorkle looks like it goes directly into that chamber :confused2:

I'll have another look then! Thanks

Edit: Doh, I see now that on post #3, there is a section specifically for XTZ... :D

That's right you won't find grease, but some will stop grit finding it's way into your engine.

Yes, the snorkle goes into that chamber. The air goes down the snorkle, through the airfilter (into the area you saw when you removed the side panels), then into the inlet manifold.

Agreed..a slight smear of grease will keep it sealed (if there's any play in the lids at all)...if you study the air box for a while you'll see just how it works and that indeed the space inside the air box is all clean filtered air....if you drill holes you'll see that the inlet trumpet will just suck in dirty air....

A different filter attached to the inlet trumpet and a drilled airbox is the only way you'll get a vast air flow improvement...

I wonder why it was made different at all?....

can someone please reload these images as i can't view them
all the best, sam
