Ok...I may be bringing up something already discussed...but it seems to me
that the 4 electrodes on these plugs would cause less spark to reach the
combustion chamber. This is kinda like indexing regular plugs....by
exposing the open side of the plug to the cylinder as to enhance
combustion...so if you have 4 electrodes...it seems to me this would hinder
the power production. If I were a 4.7 owner...I would prolly go with a just
a regular Bosch plug with a colder range than stock. OR a splitfire or..
NGK.
