[nelly]

I can dig the denso one out for you.
The plugs listed by NGK simply won't fit. technically they are specified correctly. It's down to the casting/machining around the spark plug hole that prevents them being used.
I'm not a fan of champion either. I use NGK's across all the services I do, but I bought a box of NGK's only to find they are no good.
Do you a good deal on them if ya like
