Your not gonna see any noticable gain in mpg or hp. Just make sure if and when you do buy plugs that they are the correct gap don't just take them out of the box and put them in, I check every one and there is always one or two that is off. Save up for an igniton box I just saw msd has a stacker igniton box for efi that runs something like $70+. I am unaware of its requirements you may be able to use your stock plug wires and coil, I know with the other msd ignitions such as 6A and up you need special wires but with this one I cannot say, I know it actually piggybacks off your stock igniton for a no hassle install, you may want to check it out, later
