Spark Plugs for a Roe Car

[ViperBing]

What spark plugs are people running in their Roe cars?

What about NGK Iridiums?

I run the NGK Iridiums (BKR5EIX). They have worked very well in my setup for a couple of years now. Price not too bad either at $75/set.

Well...take a look at this Dodge truck discussion on spark plugs. Some of it applies, some does not but the basic head/combustion chamber is the same as the 5.2/5.9 Magnum. I'm running the Kenne Bell recommended NGK ZFR6F11 but may experiment with the Champion Copper Plus RC9MC4 which is used in the truck V10 motor. You can read about some of the interesting perspectives...
