So currently I have some;

Champion EON 2 Spark Plugs (single prong)

They seem to be a bit mediocre to me. The car was better with the original 2 prong plugs when I bought it, for throttle response at least. I'm thinking of changing to either;

NGK BKR6EK (dual prong)

Bosch 520 Super 4 (quad prong)

Anyone had any experience in this? Thanks!

The ones with multiple tips won't make much difference to a single tip when set properly - what they offer is the ability to last longer between services. As the plug wears the gap alters, at which point another tip takes over which keeps the sparks good for longer.
