Josh-sometimes with a capacitive discharge ignition the spark intensity & the multiple spark configuration create more possibility for detonation. That`s why alot of systems require a one-range-colder set-up to be safe. It`ll also depend on the altitude where you`re living, the average humidity & the average temperature. At approx. sea level, reasonable humidity & temperatures, the stock heat range would be just fine. Where I live (@ 5k feet) + the dry, warm air, it becomes necessary to run a colder plug; each case will be different, so experiment. Hope this helps.---ROD (AZ)
I understand why you are runnin yours on your turbo colder, but what is the reasoning/theory behind runnin the colder plugs on just normal setup?
Thanks

Josh- I`m running one heat range colder on my turbo engine from what was recommended when it was an NA motor due to increased cyl pressure/heat. If I had the factory set-up, I`d run what heat range was recommended in the owner`s manual. But, some techs have recommended the colder plugs with an upgraded ignition. You pays yo` money & you takes yo` chances!---ROD (AZ.)

Why one level colder?

ok, let me get this straight, for my spark (ignition) system to be bullett proof for street use, i need to get:
MSD DIS-4
1998 RS coil pack
magnacore wires
good set of plugs, one level colder
that sound right? or is there more (less) to think about?
