How to remove the Spark Plug(s) located under each ignition coil on Dodge Ram 1500?

To get at the spark plugs underneath each ignition coil, first remove the air filter tubing as well as air intake components at the top of the engine and at the throttle body. Before removing the ignition coil, spray air via compressed air around the coil base at cylinder head. Then, using a spray of compressed air into the cylinder head opening will prevent foreign materials from entering the combustion chamber. An efficient way to remove the spark plug from the cylinder head is by using a quality socket that has a rubber or foam insert. Subsequently, check the condition of the ignition coil O-ring and replace it if necessary. In the end, take a look at the spark plug.

What are the requirements and procedures for Spark Plug installation in the 4.7L and 5.7L engines on Dodge Ram 1500?

The spark plugs used in a 4.7L engine are copper core ground electrode plugs; these must be replaced with the same type and number as original to avoid pre-ignition. While installing spark plugs in the cylinder head spark plug wells, the spark plugs must not be dropped into the wells to avoid damage to the electrodes. To avoid distortion, which may change the spark plug gap or crack the porcelain insulator, spark plugs must be tightened to specification torque. You should first carefully insert the spark plug into the cylinder head by hand to avoid cross threading then tighten to 27 Nm (20 ft.lbs.) for the 3.7L and 4.7L engines. When it comes to the 5.7L engine that has spark plugs with a design critical to torque, never exceed 15 ft.lbs. Tighten the bolts to 18 Nm (13 ft.lbs.) noting that the 5.7L does not use an O-ring. Before installing the ignition coil(s), check the condition of the coil O-ring and replace it if necessary. Apply silicone to the O-ring that facilitates the installation before placing the ignition coil(s).

The Spark Plug in Dodge Ram 1500 is the component that generates the timed electrical spark to ignite the compressed air and fuel mixture in each cylinder to start and run the engine. The ignition coil sends high voltage to each Spark Plug. The plug conducts the current to the center electrode. The current jumps the gap to the side electrode. A spark, like a tiny bolt of lightning, is formed. The Dodge Spark Plug triggers combustion inside the combustion chambers of the Ram 1500 that fires the piston downward on every power stroke. Ram 1500 ignition coils repeat this process roughly 300 to 400 times per minute at idle and up to about 1200 times per minute at cruise. The anchoring of the unit, which is a threaded metal shell, the electrode shielding by a ceramic insulator, and the sealing for compression are all built-in. With the correct gap size and heat range, the Spark Plug resists fouling, temperature control, and efficiency for many thousands of miles before normal wear appears. The Dodge driving experience is smooth and dependable for Ram 1500 operators thanks to this single Spark Plug design, which every Dodge engine in the Ram 1500 depends on.
