Default Sparking

2002 XK8 4.2 ltr. Developed slight miss fire at higher revs advised spark plug fault. So I'll change all 8 any recommendations for brand, type, ect?
Then move on to plug packs. Used Red tops in the Audi TT, worked much better at higher revs, should I go the same way with the XK?

Stock plugs work the best:

NGK IFR5N10

I can’t speak to any pros / cons regarding the coils mentioned


Z

edit: perhaps stock plugs are ND’s. I’m still sticking with the above NGK recommendation

Sorry off topic but noticed you've got a 2002 w/ 4.2 Didn't the 4.2/6 start in 2003?
