Replace the Spark Plugs or Coils on a 2011 and up V6 Dodge Charger or Callenger

Learn how to remove and replace the spark plugs and ignition coils on a Dodge Pentastar 3.6L v6 used in the Dodge Challenger, Charger, 300, Ram, and more.

The plugs and coils themselves are rather easy to remove and install. The only downside is, Dodge designed the intake manifold in a way that it covers the majority of the coils. Yeah.

4mm or 3/16" Hose (see hose trick below)
3/8" ratchet
3/8" 6" extension
magnetic pickup tool
5/8" spark plug socket
8mm, 10mm sockets
Piers

Required Parts

6 x Spark Plugs: Champion RER8ZWYCB4
6 x Ignition Coils: Mopar 5149168AI

Step by Step Instructions

Gain Access to the Coils

On the 3.6L Pentastar v6, the intake manifold covers most of the spark plug coils.

Evaluate which coils or plugs you plan to replace.

Most of them will requite you to remove the intake manifold to gain access to the plugs. Fortunately this is fairly easy - although there's a handful of connectors, hoses, and bolts to remove.

I've included a video describing how to remove it here:

1

Install a new spark plug.

I use a piece of 4mm or 3/16" hose to install new plugs. It will allow you to better feel the spark plug gripping it's thread and prevent you from cross threading. Think of it as cheap insurance against yourself.
