I'll say again: I don't think they're worth trying. I also tested them on a minivan (approximates the shape of a hatchback or wagon), A-B-A approach. No discernable effect. See: http://ecomodder.com/forum/showthrea...fect-6381.html

I was given these by a distributor. I think they cost $2.50 each new.
