What plugs are recommended for a 2006 Chrysler 300 with the 3.5L V6? I'm at 120,000 miles and car runs fine. I'd like to go with Bosch Platinum if they are compatible.

I know I also need the intake manifold gasket, anything else recommended to change while I am at it?

Thanks,

Bob

 

Use only champion platinum plugs
Replace the EGR Tube gasket it will be rubber or U will get a vac leak when install the intake back.

 

The 3.5L H.O. V6 engine use platinum resistor spark plugs. Mopar Part #SZFR5LP13G

When the spark plugs use a single or double platinum tips and they have a recommended service life of 100,000 miles for normal driving conditions per schedule A of the owners manual. The spark plugs have a recommended service life of 75,000 miles for severe driving conditions per schedule B in owners manual. A thin platinum pad is welded to both or just the center electrode end(s) .

Extreme care must be used to prevent spark plug cross threading, mis-gapping and ceramic insulator damage during plug removal and installation.

 

Thank you CHRYSLER TECH and ChryslerCares, I will make sure to get the EGR tube gasket and the platnium plugs.

Thank you both for your help, I would not have known about the gasket and would probably have gotten platinum plugs since the service life is so long I can't imagine a standard plug would be OK.

I already changed my timing belt, idler and water pump, not too bad a job. Easier than my Audi.

Hey bob,

I am in the process of changing the spark plugs on my 2006 300 3.5, question? did you remove the air intake runner all the way out of the car> if so how did you get the trans fill tube out of the way.

Thanks

 

OK,

Changed the spark plugs, just went slow and made sure i did not bend or break anything. I replaced the Air Plenum gasket, the EGR tube gasket and use the factory plugs.

 

Greetings All,

We have a 3.5L V6 2006 Chrysler 300 AWD model and I am considering spark plug replacement options. Since the intake manifold needs to be taken off to gain access getting it right the first time is a priority.

According to a local service center they prefer to use the OEM recommended plugs which they say are NGK Platinum type. Are there some known advantages for using Champion Platinum plugs? Why ~ONLY~ Champion Platinum plugs as opposed to the NGK Platinums?

Thanks in advance for shedding some light on this!

ZFR5LP-13G is OEM this one is NGK so yes NGK or champion are only recommended in Chrysler New modals of the 3.5 want NGK due to the higher temp inside the combustion chamber.

 

Many thanks CHRYSLER TECH !!! I can now proceed with confidence.
