they do look very clean. Im not seeing the color change on the ground strap though as these may be to hot. I will see as i run them. Wont be able to get to a track til end of sept, that would be a good plug test if i could. When i do go i have a set of champion race plugs with the cut back ground strap(c63cx) i would like to try.
The cut back strap is for piston clearance no?Do you like the Champion brand plug over NGK?
