Any benefit to running different spark plugs in a 2006 Dakota 4.7 Magnum?

 

as a ase certified tech my recomendation would be to stay with factory plugs. nothing you replace them with will benefit you on a stock or near stock truck.

 

and another certified tech will say stick with the factory plugs also. [sm=icon_ladiesman.gif]

 

would running other plugs hurt anything?

 

no it will not hurt anything. but just won't benefit you in any way. although i have seen some imports and ford products that run like crap with aftermarket plugs. i would stick with factory, autolite, ngk, motorcraft, or ac delco

stay away from BOSCH i have had tons of problems with their platnium plugs

 

split fire?

 

ngk would be your best bet if not staying factory. actually ngk is making some of chryslers spark plugs now. found that out recently doin a tune up on a 3.7 durango.

 

No offense, but if 2 techs just said it won't do anything to change the plugs......why would you waste the money on buying new ones then!?!?

If your truck has 100,000 miles on it, I could understand.

Changing the plugs isn't a modification or power adder on these trucks.

 

No offense, but since when does labeling yourself a "tech", give you instant internet credibility??? You could be a "tech" at Briggs & Stratton or a 12 year old ******** playing on your moms computer. I've seen more "techs" F*^& things up than I care to remember. No offense of course.

With that being said, coming from the LS1 world, replacing the stock crap platnuim plugs with NGK's has always provided a smoother idle. The platnuim pucks usually blow off after your first WOT romp.

Oh yeah, I doubt the $17.00 on plugs will break the bank. Have a nice day.

 

so from your opinion its worth it. what about split fire or those diamond fire plugs ive seen?

can any of these plugs hurt an engine?
