I picked up a Mopar Performance catalog the other day. Nothing much in
there for the 4.7's, but the plugs they had listed were Bosch. No cross
reference for that exact Champion code.
I know Autolites are good plugs. My Ducati came with Champions, but it's
standard practice to replace them with NGK's. Anybody know what kind of
unique spark plug requirements are called for with this particular
coil-on-plug ignition system?
