Where are soark plugs

Vehicles: 2000 Kia Sportage 4-cylinder 2.0L MFI DOHC 1998-2002

They're hidden underneath the coil cover, which is partially obscured by the accelerator cable bracket, which is obstructed by the air intake.

They're accessed from the top of the engine.

If you don't have a compressed air line to blow dirt away from around the plugs before removing them, one may blow through a plastic drinking straw (while closing eyes), or use a can of compressed air (with a little red plastic straw) sold for use cleaning computer PC boards/keyboards.

Where the manual (below) says "carefully install the spark plug into the cylinder head", you may consider one or another of a couple of experienced mechanic's tricks (used to avoid cross-threading the plug thus damaging the head):
trick 1: start plug by putting plug onto the end of a piece of stiff-ish hose, and
start the threads by gently turning the end of the hose. Once plug has
safely started turning into its threads, switch to a spark plug socket.
trick 2: use the spark plug socket, but carefully start the plug by gently
turning the plug COUNTER-clockwise, until the plug drops a hair - at this
point you know you've found the start of the first thread. Then gently thread
the plug in clockwise.

(3) Carefully install the spark plug into the cylinder head and torque to 11-17 ft. lbs. (23 Nm).
(4) Reconnect high tension leads to the spark plugs.
(5) Install the two ignition coils and torque four mounting bolts to 14-19 ft. lbs. (26 Nm).
(6) Install the coil cover and secure with six bolts

Where are the spark plugs located on a 2007 nissan

The spark plugs are located inside spark plug tunnels which are through the valve cover. 2007 nissan Sentras are equipped with individual coils for each plug. So to get to them, first remove all the plastic coverings over the valve cover. 10mm socket and 1/4 inch rachet with a 6 inch extension should do the trick. Before disconnecting electrical parts please disconnect the battery. Remove wiring looms for coils. Remove bolts for coil packs, lift coils out of tunnels. Spark plugs are down inside the tunnels. Use the proper sizing for plug removal. A 3/4 inch rachet with deep spark plug socket and 6 inch extension should get them out. When replacing spark plugs, thread them by hand first, usually a good 2 or 3 full turns and be careful not to over tighten. The plugs screw into the alluminum cylider head. Alluminum is soft and you can quickly ruin the threads. Installation is the reverse of removal.

You need a spark plug socket with a built in swivel and a extension to remove the spark plug. All the spark plugs can be easily removed through the wheel well as to the #3 plug also, the trick is that you need to use the spark plug socket to loosen the plug and then remove it by hand and also install by hand.

Where are the spark plugs in the 2006 ford expedition

The spark plugs are located below the 'coil pack' in a hollow tube in the head. You must remove the spark coil retaining screw to access the removal of the soark coil. The reoval with expose the spark plug at the bottom of the hollow tube in the head. The total spark coil is about 6-7" long and when it comes out that is when you will see the spark plug at the bottom of that tube. It sounds difficult to find but once you know it is easy. There is no coil wire(typical spark plug wire) attached to the spark coil. It is fed by a special connector on the side of the spark coil. Look on the side that has the least number of hoses and equipment in the way. Find the top of the spark coil (about 1-3/4-2" in dia) with a wire connected on the side. There is a single small metric bolt holding the spark coil in place. It will not come out until that screw is removed. I hope that this helps.
