How to Install Spark Plugs in a 2005 Nissan V6

Fouled spark plugs will stop your Nissan from running.

Spark plugs ignite the gas inside the engine with a spark generated at the tip of each spark plug, between the metal pin in the center of the spark plug and the small metal arm above the metal pin. The spark plugs on a 2005 Nissan V6 engine are located on the right and left side of the engine above the headers. Before you can insert the new spark plugs, you will need to use a spark plug gapping tool to set the gap between the metal pin and the metal arm for each spark plug.

Things You'll Need

• Ratchet
• Spark plug socket
• Replacement spark plugs (6)
• Spark plug gapping tool
• Torque wrench
• Owner's/service manual (model-specific)

Instructions

1. Pull the wires off of the tops of all six spark plugs on the right and left side of the engine. Remove the spark plugs using the ratchet and spark plug socket.

2. Use a spark plug gapping tool to gap the tips of the new spark plugs. Use the specifications noted in the owner's or repair manual for your particular 2005 V6 Nissan.

3. Insert the six new spark plugs into the right and left side of the engine and tighten the spark plugs to the torque specifications for your specific 2005 Nissan V6 using the torque wrench.

Tips & Warnings

• The gapping and torque specifications will be in the model-specific owner's/service manual.
