Would plugs such as the "Split Fire" line do much? They claim to increase the
efficiency (and horsepower) by more completely burning the air/fuel mixture in

about twice the price of normal plugs, but do come with some type of "money back
guarantee" (I don't know the specifics.) Are these available across the pond?
