Dear friend,

I would like to replace the spark plugs in my vehicle listed above. When I replaced spark plugs in my Chrysler Town and Country 2013 I bought Champion CCH9407, it is RER8ZWYCB4. I bought the same type of spark plug for my car (listed above), because the engine is the same 3.6V6. But when I put out the first spark plug I observed that there is other type, it is RER8ZWYPB4. I found that it is probably Champion CCH9417. Can I use CCH9407 for my car? Or should I bought CCH9417? What is difference between these two types of spark plugs?
Have a nice day,
Pawel

I attached the OEM part number that is the Champion plug that is stamped on the side of the plug. You cannot use another as the electrode depth is going to be different.

Even though the engines are the same, they changed the spark plug as they have made some changes over the years.

You can go to Champions website and cross reference this number of just order the OEM number below and you will get the correct plug. They are all over including Amazon so I would just stick with what the manual calls for.
