I'm not familiar with your layout or dimensional limitations so forgive
   me if this idea I'm throwing out bounces straight into the trash bin.

   What about a low profile flat panel filter like what the RX-8 and most
   newer cars use? You can have the open airhorns inside a sealed box with
   the panel in the cover and the inlet duct feeding into it. The filter
   panel in the RX-8 is approx. 8" W x 15" L x 1" Thick. It would take
   some fab work though as the panel would need to be secured against a
   sealing flange around the box opening for it. A K&N flat panel for the
   RX-8 is approx.$45 from Summit Racing, but K&N sells universal versions
   too if you require different dimensions to make it work.

   Yes I can make anything work. With the flat panel filter you need room
   at the top
   and bottom so it is a bit thicker than two cone filters side by
   side 3" OD and 7 inches long. With the scoop on the top of the cowl
   the air needs to make a right angle. Moving the scoop over to
   the cool side of the cowl means a long hose which is a pressure loss in
   and of
   itself. Especially if it is corrugated.

   On the Mustang II we are trying to make the cowl look like a real
   Mustang.
   Or at least I think that is what Mark wants. He has sent
   me no sketchs yet so I am not sure. Here is my best guess so far
   using a 14 inch diameter spinner. I think he wants to make his own
   cowl.

   What I really need are dimensions of different filters.

   Mark/Paul,
   Regarding the flat filter, couldn't you angle it so that the air plenum
   wouldn't have to be thicker? Just slice the box diagonally, install a
   couple of flanges, insert a filter element, and you have filtered air.

   not to confuse.)


   Good idea Mark (about signing full name :))

   Everything depends on dimensions. I'll see if I can find the K&N web
   site if they have one.

It's a tight fit in my cowl, but I think I can fit a flat filter into my
system. I'll send photos as soon as I have it fabricated- about two or
three days from now.
