The genuine-parts table says to use Mopar spark plugs. It stops there.
That is the only mark on the spark-plug row. Ignore the year number in that column because the footnote says yearly intervals do not apply.
Neither is printed. A diagram is not drawn.
The air-filter and cabin-filter rows on the same chart are different jobs. They are on the engine air filter and cabin filter pages.
No coil or cylinder diagram is drawn, because the book does not describe one.
Outbound links only. BaySheet does not sell parts. Confirm fitment on the retailer page. Amazon links are searches for a real part name plus this vehicle. Tool rows do not get a product search. The search is not a part number.
