How Many Spark Plugs Does a 4.7 Dodge Engine Have

How Many Spark Plugs Does a 2012 Dodge Ram 4.7 Have?

If you’re the owner of a 2012 Dodge Ram 1500 with a 4.7-liter V8 engine, your truck is equipped with eight spark plugs. That’s right, eight – four per cylinder. Maintaining all eight of these plugs in good condition is important to keep your engine running at peak performance, so it’s worth familiarizing yourself with their location and replacement schedule.

The first thing to know is that each plug lives inside its own individual chamber (or well) in the engine block. These chambers are sealed off from each other, so if one plug fails it shouldn’t affect the others. You can access all eight plugs from underneath the truck – no need to remove any panels or body parts.

When it comes time to replace your spark plugs, most mechanics recommend doing all eight even if only one or two are showing signs of wear. This will ensure that all the plugs are fresh and uniform, which is important for optimal engine performance. Depending on how often you drive and what kind of conditions you typically encounter (e.g., lots of stop-and-go traffic vs mostly highway miles), you may be able to get away with replacing them every 30,000 miles or so.

But it’s always best to consult your owner’s manual or a qualified mechanic before making assumptions about maintenance schedules.
