Show Planes Cowl	Accomodates Barrett Cold Air Induction Round holes ("Cirrus Look") No "ugly snorkel" Easily split lower cowl (see e.g. this FB thread)	Requires several modifications (baffles, air intake) Requires modification for optional AC compressor Stock mechanical injection engines may need modification, see this FB thread
James Cowl	Fits optional James engine plenum	Requires modification for optional AC compressor Was out of production for some time, potential cooling issues?
