Not as straight forward an operation as you might hope. First, locate the coil packs. The Infiniti has a small coil mounted on top of each spark plug. This is why you will not see any heavy gauge spark plug wires running from a coil or distributor to the obvious location of the spark plug. The coil packs are bolted down to the block with a 10mm bolt. In many cases other itesm, (air filter assembly, brackets loaded with stuff) must be removed even to see the coil packs. Be very careful with the coils as they are expensive to replace ($50+ each). The coil pack will reach down into the engine 8-10" to where the spark plug actually sits. You will need a long socket adapter to reach in and actually remove the spark plug. To change all 6 plugs, plan to spend about three hours if you have never done this before.
To change the spark plugs on a 2001 Infiniti QX4, you will first need to locate the spark plugs on the engine. Remove the ignition coils on top of each spark plug, then use a spark plug socket and ratchet to unscrew and remove the old spark plugs. Install the new spark plugs, making sure they are properly gapped, and then reattach the ignition coils. It's recommended to consult a repair manual or seek professional help if you're not experienced with this task.
