Sounds good, but I wonder if he would have the junk to run it. Eliminates the need for a cat...gosh...
yeah, something about this sreams "too good to be true." I can't see something as simple as spark plugs causing such a difference in MPG. Especially when he claims that he took his design to Bosch (I think) and they just turned him away. That's the equivilant of saying, "I took the cure to cancer to Pfizer and they turned me away because they didn't have time to market my product."
Still worth a shot though. I say that any claim is worth testing.
