The recommended spark plugs for a 3.9L Dodge Dakota depend on the year of manufacture. There's no single answer. To find the correct spark plugs, you
must consult your owner's manual or a reliable online parts catalog (like RockAuto or AutoZone) and enter your vehicle's year, make, model, and engine.
The manual will specify the exact spark plug type, heat range, and gap. Using the incorrect spark plugs can lead to poor performance, misfires, and engine damage. Don't rely on generic recommendations; always verify with your vehicle's documentation.
