I have a 2012 RT 5.7. Went to the dealer for an oil change and they said I need a 30k tune up at a cost of almost $400. I asked them why so much and they said they had to take off the manifold to reach the plugs. Is this true? Anyone did their own tune up? Any tips or suggestions would be helpful. Thanks

Manifold does not need to be removed to change the plugs. Cost of the plugs are usually $80 to $90 (16 of them). These plugs are very easy to get to on these engines, can be swapped in about an hour.

The dealer is trying to screw you. DIY project.

It cost me that for 30K maintenance for my RAM with the 5.7........

Here's a recent thread on this, many more if you do a search.

Thanks for the response. Sorry for the question, I am a newbie. So at 30k do I change the spark plugs and the spark plug wires too or just the plugs?

 

[jkelly16]

Just the plugs. Use di-electric grease where the boot goes on the plug and also a dab of never seize on the plug threads. The plugs need to be torqued also. Be sure not to over tighten them (I forgot what the torque is).

Edit: Looks like 13 ft.lbs.

FYI, when I was talked into the 30K miles service by the dealer on my '12 R/T it was about $300 (I know, too much) but they did more than plugs. They also did a complete cleaning of the intake and throttle body as well as replace the PCV valve. I watched the guy through the glass do all these things. That is still too much money for the service. I'll have to do it myself next time.

why do your RT plugs need to be changed at 30k? I've seen several threads about this. My SRT manual says 110k miles for plugs.

 

[jkelly16]

Different plugs. I think the SRT's run iridium plugs.

The intake manifold does need to come off to change plugs on the V6 - not the V8's.
The 'spark plug wire' is an integral part of the coil pack. You only change that if the coil pack goes bad or you damage the boot somehow.

Well that blows!

I won't be changing them for at least 50,000 miles then.
