  Dan Schaefer,
      I'll take your post as ment for me, and thanks...The 0.032 Al air box is
"designed" around a K&N #3260 Filter and Vans' design.. Firstly, in cold
country induction fires can be a severe problem when  over priming.
   Secondly, the Lancair supplied air box will burn (tried it)..   Got ahold 
of
Vans' plans, their box is too deep..shallowed if for the 3260 filter, layed it
out in thin carboard( pushed & shoved) as a pattern..If your Carb sits at the
rear of the sump you gotta clear the nose gear eleo with the box.. Had to cut
the lower cowl horizontally and add about  3/4" to clear the metal  air box.
Coincidentally,  this gives a larger cylinder cooling air exit, which was an
inadvertant plus..  Engine runs cool all year with gear up and hot when gear
down, air flow is the answer for me..  Don Skeele 235 /320 b-1-b
