Nice find WERM!
AS for the Afternarket, home made CAI. Yes its more for looks, unless you are replacing that 13" by 3 top hat.
I took the old hat off my durango, when I got the full K&N System put on, and put that hat onto my 93 DAKOTA, which had the enclosed tophat, along with a home made pipe and generic cone filter. Instant transformation. The Material makes the differance, Aluminum would work when wrapped in insulation. My 318 dak must have made 30 more horses, as the tire would spin too easy under same throttle input
