Installed on my 03 SS Silverado and could tell an immediate improvement in take off. I was however disappointed with the fuel mileage. Instead of gaining mpg I ended up losing about 1.5. Overall not a deal killer and an excellent value over the more expensive aluminum spacers that you can't even see under the engine cover.
