Looking for a diagram to change the spark plugs in my 2004 NBP TL. Have searched high and low with no results. Anyone have any ideas where I might find it?

Also anyone have suggestions on which plugs to use?

Thanks so much

 

There is no diagram in the service manual. You remove the engine cover, remove the coils, and then you remove the spark plugs.

The spark plug part numbers are listed in the owner's manual under specifications.

Why do you need to change the plugs, unless you have over 105,000 miles or saw the number "4" appear in the MID?

 

No need to change the plugs until 100K. When you do change them, stick with NGK/Denso Iridium Plugs.

If you wish to be conservative, the soonest I'd change them is 60K.
