Check out an earlier thread I started this week about K and N Airfilters. It has a couple pictures of some set-ups.

As far as the needs wings, that's what I'm planning on adding, however I'm planning on installing the dual air intakes. The link you have is to the single, which they say is plenty sufficient, but the dual set up looks better and adds greater flow, which they themselves say is overkill.

As far as the filters link, it looks cool but I don't see any specs nor to I really know if they are completely compatible. I put in the K and N OEM type replacements which are rated at 1/3 higher airfow than the OEMs, without having to modify. Anyway, I think what you end up with will be a matter of your personal choice. Just do it with as much info as you can -- and of course if you are targeting HP, then make sure you do the mods in proper sequence so they can be matched.

Have fun.
