'11 D R/T 5.7 spark plugs
I just passed 32K on my '11 D R/T 5.7 and according to the maintenance manual, it's time to replace my spark plugs.
Can you guys give me some feedback on what type of spark plugs should I get? Should I get just the Mopar stock? or other OEM brand like autolite, champion? What about the type, copper, nickel, platinum? Does it make any difference? Or better just stick with stock direct replacement?
mopar Part # SPLZFR5C11...shows it's actually Nickel type made by NGK. Is this correct?
thanks!!!!!

30K mile plug interval is correct. The Mopar ignition systems are very high energy. Any manufacturer that states plugs are good for 100K is BS. The only reason those cars still run after 30 K miles is that the computer adapts to the changes in spark. At 100K there is nothing left there on those plugs when removed.
Ask Ford 5.4L engine owners how they feel about 100K mile plugs almost all break off in the head when trying to remove them at 100K
At best its $60 in spark plugs every 3 years they are not real hard to do

Yes, I'm looking at the manual toward the back that says 32,000 miles...replace spark plugs along with oil change + filter, air cabin filter, etc.

Can't get the pic to upload but you should check with the dealer before going to the hassle
