Use a spark plug wrench to remove the old spark plugs. Be careful not to overtighten the spark plugs when you install them.
Step 4: Install the new spark plugs
Install the new spark plugs into the cylinder head. Hand tighten the spark plugs until they are snug. Then use a spark plug wrench to tighten the spark plugs a further 1/4 turn.
Step 5: Replace the rubber boots
Replace the rubber boots over the spark plugs. Make sure that the boots are seated properly.
Step 6: Replace the engine cover
Replace the engine cover on top of the engine. Tighten the bolts or clips that hold the engine cover in place.

2005 Pathfinder 4.0 Firing Order
The firing order for a 2005 Pathfinder 4.0 is:
1-6-5-4-3-2
This means that the cylinders fire in the following order:
- The piston in the first (or front) piston in the engine is at the top of its combustion and the forces from the combustion drive it powerfully down.
- The piston in the back of the engine with the next most completed combustion cycle (6) begins its powerful down-cycle.
- The next most completed combustion cycle (5) is at its power-down at the same time. This is useful to keep the crankshaft from slowing down excessively at TDC and BDC and to help keep the valves timed properly.
- These three are followed by three more power-down strokes of pistons, in succession of their "closness" to TDC just before the the first one began its combustion.
This firing order is important for the proper functioning of the engine. If the firing order is not correct, the engine will not run properly.
