I have this same car and this is how I do it. You will be removing the throttle body. Before starting, make sure the engine is cool. ( There are two coolant lines to the throttle body to help heat it up and keep it from icing in cold weather. You can elect to drain some of the coolant out of the radiator or just keep some rags handy under the lines when you disconnect them. Some coolant is going to drip either way---less will drip if you drain the radiator halfway before starting. )

Begin by removing the black air intake "elbow" from the throttle body at one end and the air flow meter at the other end. Label the three vacuum lines on top of the throttle body and push them off of their respective nipples with a flat blade screwdriver. They may tear if you pull them off. Next, disconnect the electrical connector from the throttle position sensor on the front of the throttle body by using a very small flat blade screwdriver and pushing on the two ends (one at a time) of the wire spring clip while gently pulling on the connector. Be gentle, the plastic on the connector is old and brittle.

Next, push off the end of the large engine breather tube next to the Throttle position sensor on the front of the throttle body. ( Use pliers to slide back the retaining clip if one is there.) Do the same to the PCV hose on the back of the throttle body. Now remove the medium sized coolant hoses from the throttle body. use rags to catch the small amount of coolant released when these are disconnected.

Push the throttle rod off of its ball stud on the back of the throttle body. You may have to pry a bit with a screwdriver to get it to come off. Remove the two black metal brackets on the passenger side of the engine holding the throttle body. Remove the brackets entirely not just the bolts on the throttle body.

Now you can access the four bolts that hold the throttle body to the air intake plenum. They are 12mm and you'll need an extension to get your socket into the deep wells where the head of the bolts are. The throttle body should come out easily. There is a metal gasket between the throttle body and the air plenum that can be reused. Once you get the throttle body out of the way, you can get to those middle plugs. If you have problems, write a comment on this thread and I'll check back later to help.

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.

How to change spark plugs


Not a big deal.

I am assuming that the engine is a V6. Realize that the plugs from the factory are Iridium and are good for 100K miles. Assemble the following:

6 Denso IKH20 Iridium Plugs pre-set to .044 gap ($10 each)
High Temperature anti-seize (crayon type is $3 at NAPA)
3/8 inch drive ratchet
5/8 inch spark plug socket
4-inch extension
10-inch extension
10 mm socket
12 mm socket
torque wrench (or make real sure you don't over tighten the plugs)
new air filter (optional)

You DO NOT have to remove the center cover over the engine to gain access to the spark plugs.

Start on the passenger side. Disconnect the air induction/filter assembly by un-snapping the two spring latches on the black air intake box closest to the front of the car. Once these are un-latched, fold the air intake assembly out of the way. Now would also be a good time to replace the air filter if you have not done so lately. With the air intake assembly out of the way, you now have clear access to the top of the valve cover. Along either side on top of the valve cover you will notice three black modules each held in place with one 10mm bolt with a small wiring harness connector attached. These are the coils (one per plug), and the spark plugs are located underneath. Disconnect the wiring harness connector and remove the 10mm bolt. Pull straight up on the coil and it should disconnect from the spark plug. Look down the hole and you can see the top of the spark plug 5 inches down. Using a 5/8 inch spark plug socket with a rubber 'holder' inside the socket to hold the plug, remove each plug. I had to use a 10-inch ratchet extension to provide sufficient clearance. I know it sounds goofy using a standard size socket on a metric car, but it is what it is. I make sure I get each coil back to its original location, but it really does not matter as they are all the same. Since the heads are aluminum and the spark plugs are stainless steel or monel/nickel, you have to be careful not to ruin the threads on the heads. I ONLY remove the plugs when the engine is cold. Apply some high temperature anti-seize only to the threads on the new plugs and install to 18ft-lbs of torque. Slip the coil back in place, attach the connector, install and tighten the bolt and you are done with that plug. Repeat for each plug. Re-install the air intake assembly and snap down the two latches and you are through with that side.

The driver's side is more difficult as there are things in the way. I had to remove one bracket (held in place with 2 12mm bolts) and disconnect a rubber hose underneath that bracket (it just slipped off with little effort - no tools required) in order to provide sufficient room to remove the coils. This is not as bad as it sounds, and I had both removed in under 2 minutes. Now you have access to the coils and plugs and can repeat the process. Go slow, take your time, don't get anti-seize on the plug firing tip, use a torque wrench if you have access to one. Replace the hose and the bracket and you are done.

Total time is 1 hour if you are not mechanically inclined, 30 minutes if you are

Where is the coil located


This car has a coil pack. All six spark plug wires connect into it. It is located behind the air intake maifold. To get to it: (what I did)
1 Disconnect wires and hoses around the air intake area. Start at the air filter and go along to the air manifold. Loosen clamps at filter.
2. Loosen the clamp and remove the air intake hose. It justs comes loose. I left it in.
3. Disconnect the air valve (has butterfly valve). I forget the proper term. Just move aside.
4. Finish disconnecting hoses, i.e. pvc, EGR vacuum.
5. Remove the two nuts that hold the EGR valve to the pipe. Leave EGR attached to air manifold.
6. Remove the eight bolts that hold the air manifold.
7. Final check for anything still attached. Remove if needed.
8. Remove air manifold. You are exposing the air ways into your engine. Cover or stuff w/ paper towels to prevent getting contamination.
9. Now you have access to the coil pack. Three bolts.

If you have not replaced the plugs or wires, NOW is the GOLDEN time. WHILE YOUR in there.
Whether new wires or old, watch the transfer to keep in proper sequence.
Reverse order to put back. Use a bolt tightening pattern that pulls the manifold down evenly.
You may need a new gasket on the EGR connection.
Good Luck.

Spark plug location in a 2001 ford escape


Need to remove upper intake manifold to reach valve cover close to firewall.
1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires).
2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold.

Chevrolet trailblazer 2006 engine spark plugs


Platinum (or more precisely-AC Delo Iridium) spark plugs. The six spark plugs are directly under each of the six coils on top of the camshaft cover. The air intake needs to be removed, then each of the 10mm bolts for the individual coils. The coils can then be removed and the spark plugs accessed.

Change sparks plugs on 06 hyundai sonata v6


You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

Change Spark Plugs on 2002 Mitsubishi Eclipse GT V-6 (3.5)


First off, you don't have to remove the WHOLE INTAKE MANIFOLD. If you look closely, you'll see that the intake manifold is a two piece setup(Upper Intake, Lower Intake).

You will need a new gasket after removing it. Don't be cheap either, get one that is reusable.

First, remove the air intake from the restrictive airbox, then remove the bolts from the center portion of the intake not from the heads!!!(This is not a Chevy so the car's parts made on this intake is for people like us to work on)

After removing the "Upper" intake and everything else including any hoses, you may successfully remove the intake and lay it aside and guess what, you can replace spark plugs.

Replacing the front three is a no brainer so I'm not getting into that LOL. NOW, I HIGHLY suggest to go ahead and spend the extra $20.00 or $30.00-$35.00 if you was performance gains and better/longer performance usage, and get you some plug wires too. You only want to do this once (For a long time).
Do not use any other spark plug but an NGK brand, NOt an AC Delco although they call for it too, I wouldn't go with them. These stout V8 killer motors produced were specifically made for high performance.

How to change air filters on 2007 Mercedes C230 Sport


I have '05, both should be similar:
1.Cabin air filter is located above battery on right side against firewall.
Release three latches, remove filter housing, slide old filter out (housing is flexible), insert new
one, reinstall housing.
2.Engine air filter is on the left side of the block (follow intake hose). Cover is retained with six screws
(six point star shape,I belive called Torox, bit/scredriver size 25). Loosen screws (don' t pull all the
way out of the cover) lift cover , and remove old filter. Insert new one, reinstall cover. DO NOT
OVERTORQUE SCREWS! Screw holes in plastic filter housing strip very easily.
Note: Intake hose is very flimsy, one on my car came apart and had to be replaced.
