I'm pretty lazy about filling the tank, I wait until the low fuel light goes on before I fill up. If I'm doing alot of city driving it'll come on between 290-300, if I'm doing highway driving I've seen it get as high as 360 before the fuel light came on, this was just last week with 53k on the clock original plug / wires. Are the aftermarket plugs / wires going to give me any economy bene's?
Thanks,
