Hi,

What spark plugs are ‘best’ for a 4.6 V8?

Cheers!

I use NGK B7ECS in mine, and this seems to be widely recommended for all the later RV8 powered TVRs. (On the earlier 'wedge' models, the usual recommendation was one grade hotter i.e. a 6.)

Thanks!

Someone else has just recommended NGK BP6ES's.

What the difference?

Cheers

Slightly different shape and one grade hotter.
