Just bought 16----RE14MCC4 Champions from Sparkplugs.com for 2.32 ea.-----50.33 out the door. Its time for mine too at 90K.

 

i work at a dodge dealership and i see them every day

 

See what everyday?

 

it would be interesting to discuss with a Chrysler engineer(s)
why they put two different styles of spark plug designs
in the new twin plug 4.7 V8

several years ago there was an article
where a bigwig at Chrysler said that a American/German meeting
between Chrysler and Daimler employees
where information was shared about
twin sparkplug design features
led to surprises and 'Ah-Ha' moments on both sides of the Atantic

 

i see the 4.7L rams and hemi rams every day at the dealership

 

they told me that having dual plugs in each cylinder and firing hem both at the same time gives you a better burn which of course gives you better horsepower and torque
