Before starting get only ford wires and spark plugs.
Mazda or Ford dealership will have the stuff. Replace both together.
Use dielectric grease as well and gap the plugs correctly.
For the 2001 you will need to know your VIN, as they changed the coilpack midflight, so there are two types of wires. One has clips, and the other just a push on.

You will need some socket extensions and a spark plug socket with rubber catch inside.

Step 1. Remove IMRC module 3 10mm bolts, move carefully to the side.
It is a rectangular box low right side with 3 bolts.
The front 3 plugs (cyl 4, 5, 6) is now exposed to replace.

Step2.
The rear plugs look hard, but not so bad.
Unclip the coil pack wire. Depending what kind of coil pack you have there will be 3 or 4 bolts. 4 bolts if you have clip on wires, or 3 if you do not (2 on the left side, 1 center on the right). I think they are 7mm, can't remember.

You will need a short extension. You will be working a little blind, but it is not so bad. Point a flashlight in there. Pay attention to the ground strap on the right hand side, it comes off one of the bolts when you unbolt the coil pack. Once you get the coil pack out of the way it easier to get the plugs.

Use a long and short extension combination for the rear plugs (1, 2, 3). Once again you are working blind, but it is not hard at all.

You cannot use the sparkplug socket to put the plugs back in as the rubber inside will keep you from geting your socket out.
I use a rubber hose over a plug to drop the plug in and start the threading, then I use a regular 5/16th socket to tighten. Use some anti siege on the threads. Do not over tighten.

Pay close attention to the numbering on the coilpack. It is marked on the coilplug, otherwise you will screw up.

Put the coilpack back in. Remember the ground wire on the right, and some other gizmo on the left when placing the bolts back in.

Install the new wires. Trasnfer the wireloom from the old wires to the new wires (only if origional wires, you mat not have a wire loom).

It is not so bad. Most of time is just fidling around with extensions.

Good luck.
