Where are spark plugs on 2008 Dodge Avenger?

Depends which engine you have, V6 2.7 or 3.5, or a 4-cylinder but either one will be underneath the intake manifold or underhood engine covers. Need more information to tell you for sure.

A 4 cyl. So it's under the shroud or engine cover? I see an intake manifold type looking cover in the front of the engine,It's black. Thanks, Sue

How do we change the spark plugs in the intake manifold. It seems so complex
