Interesting pictures Bill. Here is what my installation looks like.
You will note the snorkel is absent. For some reason or other your installation seems to have a little more clearance on the right side than mine. But I can’t figure out why. The 993 cover appears to be a little shallower, but that may be just an illusion.
The cold air thing is intriguing. As I am currently w/o A/C I’m thinking a duct could fabricated between the old snorkel fitting directly up under the engine air grille. I have significant experience in fiberglass fabrication and could definitely do it. A project for “down the road.”
