Or maybe the director give you the tattoo.

I think the cold air snorkel intake is a big no-no. For better fuel economy the generally accepted wisdom is a warm air intake. Plus of course it'll just present that much more resistance to the wind, also not helpful.

This should prove interesting. I look forward to seeing how it develops.
