Spark Plug question HOT OR COLD
I am looking to run "colder" spark plugs in my car to accompany a supercharger. I have some new bosch Silber W7DSR Plugs. Are they considered cold? Any recommendations for colder plugs?
How do WR7DC and WR7DS compare to these?
I've been looking for conversion charts without much luck.
cheers
