1) use screwdriver to loosen two duct clamps; the air filter duct at the resonator box, and the clamp nearest the throttle body (leave short duct connected to resonator if you can).
2) pull the air filter side ducting from the resonator.
3) remove two 10mm screws holding the resonator box, they are below and to the rear of the air duct and are rubber mounted.
4) pull-off the hose at the right-front of resonator box.
5) as you lift the resonator box upward, work loose the TB ducting, also remove the vent hose underneath the box near the rear (it just pulls off, may need to loosen by a little prying).
6) you should now see the five tear-shaped coils, each with one 10mm screw.
7) it is better to remove the wire connector from the coil first, squeeze hard and pull (or carefully remove the coil, 8-9, to get underneath connector and remove it).
8) remove 10mm captured screw until it is loose.
9) pop out coil from valve cover, and note the deep hole with a plug at bottom.
10) first, clean area around hole and clean gasket around coil, second, blow all with air to remove loose debris; then remove plug with ratchet and extension using a proper spark plug socket.
11) once plug is removed, squirt brake cleaner or carb cleaner into hole to clean plug seat and threads (this will get into cylinder and may initially cause difficult starting).
12) carefully install new plug; use fingers and socket extension to thread until seated.
13) tighten plug to spec.
14) look into rubber boot of coil; use needle nose pliers to gently pull the coil high-tension spring back to its full position just below the opening, do NOT pull hard or stretch the high-tension spring.
15) look down the plug hole, and align the boot with the plug and proper bolt position; push down until coil seats properly then tighten 10mm bolt.
16) reinstall coil wire connector.
17) perform this 4 more times for each cylinder, note that the front cylinder may be a bitch because it is partially covered by wiring harness -- try open-ended 10mm wrench and completely remove the bolt from the coil (just pull up, and continue unscrewing) -- or, try and pop wiring harness loose.
18) once all five cylinders are completed, reinstall resonator box and ducting (don't forget tube underneath box).
19) reinstall hose at front-right of box.
20) start engine (it may take a few or 10 tries to get is running) -- don't hang on the ignition key while starting, short bursts are best until cylinders clear.
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
on the 3.5 v6 take off the engine cover, unscrew the coilpacks and take out the spark plugs.
Changing spark plugs is relatively easy. Disconnect the batter and spark plug cables, and remove the old spark plugs. Next replace the spark plugs with new ones, reconnect the spark plug cables and battery.

On the 2005 Saturn Vue, the spark plugs are located on the engine block, specifically under the ignition coils. If the vehicle is equipped with the 2.2L four-cylinder engine, you will find the spark plugs on the top of the engine. For the 3.5L V6 engine, the spark plugs are located on the sides of the engine, requiring the removal of the engine cover for access. Always ensure the engine is cool before attempting to locate or replace the spark plugs.

To replace the spark plugs in a 2005 Mazda Tribute V6, first, ensure the engine is cool and disconnect the negative battery terminal. Remove the ignition coils by unscrewing them and carefully pulling them out to access the spark plugs. Use a spark plug socket and ratchet to remove the old plugs, then install the new ones with the correct gap, tightening them to the manufacturer's specifications. Finally, reattach the ignition coils and reconnect the battery terminal.
To replace the spark plugs on a 2005 Mazda 3, first, ensure the engine is cool and disconnect the negative battery terminal. Remove the engine cover if applicable, then carefully detach the ignition coil connectors and bolts to access the spark plugs. Use a spark plug socket to unscrew the old plugs, and install the new ones by hand tightening initially, followed by a torque wrench to the manufacturer’s specifications. Reattach the ignition coils and connectors, replace the engine cover, and reconnect the battery terminal.
