I only understand concrete numbers. I'm not much on the theory of why this 
or that works. Why does a 350hp corvette engine get 29MPG highway, and my 
115 hp Audi only get 27-28. I don't know all the answers. However, seen 
before and after #'s from two friends cars, and both improved. The honda 
accord 4-cyl went up 2.5 mpg, and the Grand prix went up almost 3mpg. They 
were both installed significantly upstream of the engine. I'm thinking maybe 
the swirling continues downstream.

Really, I'm perplexed, I just know it worked in those cars.

Oh, and my honeycomb screen is gone, bye-bye. No idea where it went!
