I would say this product is probably not going to be a noticeable improvement in and of itself. Overall with this as well as doing a few other things to lower your BATs you might see a small improvement.
as blender cloud said its part of a bigger equation in lower BAT's. this with a coolant bypass on the tb, and a phonelic(spelling?) spacer for the intake manifold. and prolly some other stuff i cant think of right now.
