Dont bother upgrading to Bosch super 4. Stick with GM or NGKs. According to the majority of the members on Migweb.co.uk, Bosch super are "crap" and GM plugs are one of the best, along side the double core NGKs.

I cant see why the Bosh 4's would be crap or would burn out a coil?? In fact I think thats imposible? spark plugs dont pull power they just provide a calibrated gap for a spark to jump across.

I thought the idea of four cathodes was to maintain, for the longest period posible, a correctly calibrated gap. As the electrode has four cathodes to choese from it would have like four times the service life? As lighning chooses the shortest route, when the gap to one cathode becomes bigger from wear, the spark will move on to a diffent one. Just in case anybody thought that the spark splits in to four and hits each cathode at the same time your very wrong.

Does anybody hear have a rolling road? it would be intrested to see a power curve for diffrent plugs and I put money on it not changing.

got to say, i changed my gm ones for some bosch 4 plugs, and the change was...er.....well - there wasnt! People expecting performance from a plug, you'd need a very high performance model with poor plugs in it to notice a difference.
