Things You'll Need
Pliers
Socket wrench
Spark plug socket
Replacement spark plug(s)
Anti-seize lubricant
Torque wrench

Instructions
1
Disconnect your negative battery cable. 2001 to 2006 models have a plastic engine cover you must remove to access the spark plugs. Pull this cover off, if equipped.

2
Label the spark plug wires per their position before removing them. If replacing multiple spark plugs, it's best to change one at a time to avoid getting the wires cross-connected. If your Mazda Tribute is equipped with the 2.3 L or the 3.0 L engine, please see the Tips section.

3
Twist and remove the spark plug boot to access the spark plug. Use the socket wrench with the spark plug socket to remove the spark plug. Removing the spark plug without this tool is possible, but will increase the chances of damaging or stripping the head.

4
Apply a small amount of anti-seize compound to the three lowest threads on the new spark plug. Do not get the compound on either tip of the spark plug.

5
Loosely tighten the spark plug by hand, and then use the torque wrench with the spark plug socket to tighten the spark plug to 15 foot-pounds of torque. This level is acceptable for all model years and all engines.

6
Replace the spark plug boot and reconnect the negative battery cable. Replace the engine cover, if equipped.
