[V8] spark plugs

[Z1 Performance]

What plug does everyone recommend...I think I might be running the wrong ones!  I have had an intermittent miss since I started driving it, and the cold start stinks.  We did new cap and rotors (wires looked ok at the time), air filter, fuel filter, etc when I first started using the car this winter

thanks!
