John Slade has a Cozy with a 13BT (and air conditioning!). He's one of 
the few folks I know who hasn't had overheating issues. He has a 
standard Cozy NACA scoop feeding into a plenum formed by a large flat 
radiator mounted horizontally forming the top of the plenum, stock Mazda 
oil coolers on the sides, and a "door" at the rear that he can open like 
a cowl flap. It's not a variable intake, but the variable exit serves 
most of the purpose of variable intake and is much MUCH easier to make.

It works really well for him ... Jim S.
