Manifold cooking?

[servermonkey]

Shannon Burke talked about Manifold Destiny: The One! The Only! Guide to Cooking on Your Car Engine! a few days ago. Strangest thing I've ever heard of, and I was reminded of it by Syreene's post about vehicles that used cooking oil for fuel.

Additionally, there are apparently all sorts of other gadgets for vehicles nowadays. One caller suggested running a tube from an A/C vent inside the car to a modified cooler, so you can keep your beer ice cold, obviously.
