Hahaha, have fun with the fuel injection restrictor pal. Your car will run like a turd. Why would you buy a V6, then put a so called "fuel saver" on it. All it will do is restrict the flow of fuel to your injectors, and your car will drive like a haggard rat. Why not just buy a 4 cylinder if you are worried about the already low fuel consumption of a 3.8L Ecotec engine?
