Diamond Aircraft has fiberglass oil cooler diffusers (they call them 
"plenums") that they use on their Katanas.  They looked pretty nice at 
Oshkosh, where I saw one installed on the Continental engine with FADEC 
installed.  I didn't get to see it on the Katana because they had the cowling 
on.  It has a round inlet for SCAT tubing, making a 90 degree bend and 
transitioning to a rectangular outlet which attaches to the cooler.  It 
looked like a lightweight part painted with speckly black paint, like 
Zolatone.  Not a prize-winning showplane part, but perfectly serviceable.

Their family of aircraft uses two different oil coolers, the Stewart Warner 
10568 (Positech's equivalent is #4212) and the Stewart Warner 10599 
(Positech's equivalent is #4215).  The Lancair 320/360 uses the latter (10599 
/ 4215).

The Diamond part number for the plenum for the 10599 / 4215 cooler is 
22-7923-10-00.  The price is $168.92.  You can order it through Diamond at 
(519) 457-4041.  Push "2" to get the parts department.  There is presently a 
three-week backlog.

At that price, I'll probably make my own....unless Lancair can cut us a nice 
deal....
