More the better, yes better for shroudign the spark which isn't good!

The only use multi electrode plugs have (apart from throwing away) is longer service life.

The spark only ever jumps to 1 electrode (the closest one).

A single electrode is much more open and exposes more of the spark to the mixture.

Think of it this way, throw a match in a swimming pool of petrol it will all burn, but throw in a basketball on fire in and it will burn quicker.

Also I have to say this, I find bosch leads crap, I have a large pile of bosch leads, they usually fall apart. Magnecopr KV85's are well worth the money and the 10 year warrenty.

i had some S4's in mine and they were ok, dont expect miracles though.

electrity will fith the shorts route to earth out so havein 4 prongs it will choose the closest but the spark will be weaker, single prong plugs ar better as you can gap them and you will get a much stronger spark froma sinlge prong one

i just use the standard vauxhall ones as i find they are better. probably bosch ones in reality. but as was said earlier don't shroud the plug as then it's harder to ignite the fuel/air mix and that ain't good for power.

i have, all you need to know is bloody expensive!!!

really they are.

the platinum is there to resist higher temps as more modern engines are run closer to detonation i.e a very lean mixture to get good fuel economy which leads to high combustion temps. all because of cats. damn things should never have been allowed
