I tried these sorry nothing nada zip but I had a 4 banger. I think I go with Tony.

Fundamentally, once the mixture is lit, it's lit. A fire doesn't burn hotter because you use a bigger match to light it; a bigger spark won't make the fuel/air mixture burn any hotter either. I have carried out many engine experiments involving changing ignition energy, and while there are some marginal benefits in extreme conditions (cold, damp, etc), the overall effect on power and fuel consumption on any modern engine is negligible
