C 6 spark plugs, and maybe plug wires ?

[Fatbloke-Dim]

Any advice on the best U.K. available spark plugs ? And if you'll pardon the pun , any leads as to replacement plug wire sets ? Have heard that certain NGK plugs have resistance values that have caused issues with the ECM leading to poor ignition performance and power loss. Seems that Bosch equivalents may be widely available, but ....any good ?

FYI
NGK was bought out, so under the name of new ownership

I know for my C5 I have used the NGK TR6 for 20 years, for street and racing and never had any problem using them

If you want to know which ones and type is, put your car info here, and it will show you which ones for your C6

Very happy NGK TR6 user for many years, I change them every 3 years, perhaps to often, but they are cheap compared to the iridium tipped ones

or you could just get AC Delco ones

Delco stock spark plugs are not the correct heat range or gap when installing performance mods,
worse when engine compression is raised, adding any type of boost, headers etc and the flame gets blown out
or hotter cylinder temps with stock gaps
