Perpetual movement is impossible.
you always have a restriction, so you always need energy.

Hey Doherty it's Jibs....Anyway, come on buddy you honeslty think a new set of plugs is going to make that kind of difference.. Maybe if the old plugs are in real bad shape or your switching to Splitfire plugs or something. I just don't see that happening if your old plugs were still in good shape, are you sure? Did you change your wires out at the same time? I have changed plugs out a few times on several SC's using bosche plugs over the years and never noticed a damn thing...WDoherty said:, these plugs will give you a legitimate 2-3mpg boost as from what i read most with sc's get around 22. Of course with your higher gearing in the LS you'll get even better.
Don't know but I seriously dought it unless a poor running motor causes premature spark plug destruction...From your discovery you maybe onto something, I have been using cooler temp nos autolite plugs so I cannot comment on the differences......By the way how are you able to measure 22mpg before and the 25mpg after?WDoherty said:Well i want to say they weren't that bad because i always got 22mpg with this car even when i bought it with 87000 miles and it had the 60000 miles service done at 63000 which included factory plugs. So do you think factory platinum or iridium (i can't remember) would go bad within 15000 miles?
