So old skool copper is just fine
the old skool copper is just fine, and NGK's all the way here too, exactly right.
i'd normally be an advocate of dropping the "R" from any plug listing too, bugger the neighbours television, its all digital now anyway, gimmee the spark without the resistance!!! ha ha!
what will it be for you Brit NGK BP6 or 7es?
i looked at the nology silvers some years ago too, and the majority of the website info and theory is bang on, particularly the bits about the use of iridium and platinum etc, very true indeed, and i wouldn't fit them as a gift!
same approach as engine oil in my case, fit what works, save the money on gimmicky liquid gold stuff, but change them much more regularly, and that way benefit from having tip top fresh plugs, fluids, filters blah blah all the time, and no risk of any part of it being degraded in any way.
ps - chris, aren't you ready for another sprint yet?
