I have a 94 m6 z28 with 160k on it, I am getting new wires, opti, and coil and wanted to know the best plugs to buy for the car. Last plugs i put in it where platinum +4 and i later heard that the lt1 doesnt really like those.

Any suggestions please so I can order the parts. Thanks

Im going to run msd wires 8.5's , with msd blaster coil. and msd cap and rotor kit.

 

NGK TR55's

my car with 145K run soo smooth with them.
