I have 6" X 1.75" pancake-style K&Ns on my BJ8. The rear filter has the holes
in the center, the front is a custom-fab
with the filter riding as low as possible. Still, the front barely clears the
shroud and the fresh air duct. My
guess--this is only a guess--is that the thickness might give you trouble on
the front filter. Or, since the top of
the frustum is smaller you might be OK. Hard to say--you might try measuring
the clearances or fabbing a mockup out of
styrofoam to see how it'll fit.
The typical K&N setup has stainless plates for the top and bottom of the
filter. You'll need some kind of plate to
backstop the bolts. I'm using stub stacks from APT (www.aptfast.com). You
might give David Anton at APT a call and see
what he thinks.
I fitted the K&Ns after driving through a dust/sand storm in Death Valley, and
imagining all that grit getting into my
engine.
