DZ Spark Plugs?

[YENKO DEUCE REGISTRY]

I use R45's for the street and cruising, but re-install R43's for SCR racing - remember the spark plug delivery to the meet-n-greet in the parking lot by the local Chevy dealer?

I have fouled several sets of R43's, (not my NOS set of 4 thin lined ones though), and found that the hotter R45 worked much better. I will give the NGK's a try though, as the R45's will foul occasionally too, especially after idling in line at a cruise or a show.
