Plugs at 30K. All 16 of them? The owners manual should be required reading before purchasing the Hemi. I have a ford Taurus that just hit 100,000 miles and I have never changed any plugs. The car runs as good as the day I bought it. The mileage is better.
16 spark plugs! What the F**K where they thinking. I do not know much about engines and rolling mechanical work, so I will be needing the dealer to perform the maintenance.
I probably still would have bought the truck, but I definitely would have asked many more questions before I signed that check.
They were thinking two spark plugs ignite the air/fuel mixture much better than one. Simply put, the more even the burn the more efficient the engine is.

Do I have 18 spark plugs? The maintenance schedule shows the 4.7 liter needing the top plugs replaced at 30K, and the 5.7 liter all the plugs. I have the 5.7 liter. So, will I be changing 8 or 16?
Can I go longer than 30K with better plugs? Like I said before, my other vehicle has plugs rated for 100,000 miles. Could I use this type. And how would this affect my warranty? (provided I still have one). Thanks John
16 plugs every 30K. Sure, you can go longer. I can also eat that piece of pie after dinner even though I am stuffed, does not mean I should.
I will be interested in how bad the gaps are when someone does them at 30K. The consensus on the coppers at 30K was because they were copper. Given the new GEN Hemi is Platinum maybe they will last longer. If the Platinum gaps are large at 30K that would indicate it is a Hemi thing.
Actually you'll only need 16 plugs. And I did skip right over the 30k maint schedule. Pages were stuck together but didn't notice last night at 11pm. So what type of plug is the LZFR5C-11, copper, platinum? Has anyone purchased these yet and if so where and how much each? Thanks.

if you are getting the dealer to install them, then yes you will have to change them all (the dealer is going to screw you and change them out)
if you check your plugs yourself and as long as they gap is still the same and have no corrision or defects then you can still run them.
just because your truck hits 30K doesnt mean it HAS to be changed. its just an average number for an average truck that might need to have the plugs changed.
the only way it would effect your warrenty is if you didnt change your plugs when they defective and caused harm to your engine.

The relatively short interval (by today's standards) is for the aluminum heads and not so much the spark plugs. My 03 still has the original plugs and it runs fine (90K+miles) and I am a little worried because of the heads. Most modern plugs can go to 100K miles easily. The risk is damiaging the realtively soft aluminum heads with the steel spark plug threads becoming welded together. I will change the 03 soon and then I'll know if there was an issue.

If I did change mine myself which I will not do, I would use anti-seize on the threads before screwing in the new ones. I learned a long time ago to do this. Since it's only 30K now it may not be such a big deal. 100K, anti-seize for sure. Those buggers can be a real hassle to remove.
