what are the oem plugs for the 5.7 hemi?

 

while were on the subject, anybody try any aftermarket plugs with good results?

 

i here the iridium are best. anyone know the pros and cons of msd wires? will the hotter spark damage the truck?

 

OEM plugs are Champion RE14MCC4. Remember, the Hemi has 16 plugs.

 

iridiums are good but very pricey at $6.00 each, i know a guy that has that exact combo of wires and plugs, and he doesnt seem to any problems with his truck

 

are platinum plugs a no-no for the hemi? i hear the tips can come off. true or not?

 

i called several dodge dealerships and all said not to use platinums in the hemi. why? im still not sure. im going to guess that the platinums are to hot.

 

I haven't ever seen or heard about the tips coming of the plugs, but I have fixed some driveability problems by replacing aftermarket and platinum plugs and installing the original plain champion plugs. Some people get by with different plugs and don't have any problems and there are alot of different opinions, but I generally like to stay with what the vehicle was designed and set up to use.

 

Man, I just got done replaceing these and now I am having some homiceidal tendencies towards the engeneers. Is this normal?

PS take the entire air induction off to do this it gives a hell of a lot more room

 

Anyone tried the E3 Square Fire plugs?
