Bosch Spark plugs information

[Raindancer411]

Hi all, been a while since I posted here but wondered if anyone could help shed some light on information for bosch's spark plugs. Tried looking at their website and nothing there, and other than calling or writing I cant seem to find out.

Boyfriend runs a MG midget race car and previously brought some Bosch Super 4 WR 78 X spark plugs from Halfords. Went to buy some more today and they didnt have any other than WR 78 G or WR 78. Does anyone know what the X and G stand for and what the difference is between the three WR 78, WR 78 G and WR 78 X???

Thanks

I cant answer your question, other than to say. Just buy some good NGK plugs.

IMO, Bosch are crap.
