I am going to carry out a full service this weekend ready for the winter and wondered what plugs were gd for a modded g40 engine.

advice would be appreciated

thanks zack

Bosch W5DP0 are the ones to use.

[Tommo]

Or NGK BP7 EVX, which are cheaper and probably superseed the bosch ones.

cheers zack

I wouldnt use the NGK ones. mine melted every time i went above 120. as soon as i put tyhe Bosch ones back in i never had a problem, now i can blast past the 120 mark with no worries

You've got a problem then- try a colder grade. The NGK are by far a harder plug than the Bosch.

[Tommo]

Yeah, and the Higher the number the colder the plug IIRC, so try 8's. But I dont see a reason why you should have to.
