standard I meant

What year is the engine and are they still stock heads? I would still suggest a projected tip but I would go one heat range colder and close the gap.

Any questions call me at work (ngk) at 248 926 6315

Got a NGK part number? I have a bone stock headed 5.0 too but am going to run a 150 shot.

I know I used TR6's in my Z28 before and loved them.

The stock plug should be a UR45 so I would suggest two heat ranges colder and a non projected tip for a 150 shot. plug number is BR6FS stock# 4323
