My 2002 Kia Sedona currently has 34,000 maintenance-free miles. Would like to know if someone has replaced the spark plugs and can provide instructions on how to do this task.

make sure you buy new ignition leads because they can break when removing them from the spark plugs. The front (cylinders 1, 3, 5) are easy to get to with 3/8" drive sparl plug socket, an extension bar and ratchet. As for the back 3, put the vehicle up on stands at the front, grab the spark plug socket, a short extension bar and the rachet, crawl underneath the front of the car on your back and start swearing. 2 hands are required. First off, remove the plug leads by a small twist then pull. This is where the plug lead might break. Once the ignition leads are out of the way (yes, even though they seem to come up hard against the firewall - by manipulating them they can be removed), drop the plug socket down the hole onto the spark plug, feed the short extension bar into the hole and click it onto the socket, then feed the ratchet up to the extension bar (2 hands) and proceed to loosen/undo the spark plug. If you don't have the socket with the rubber piece in the end of it - to grip onto the plug, then you will need a thin magnet to drag them out with. Reverse the process for installation. This might seem long winded, but it's the ONLY way to do the back 3 plugs. They are also platinum type plugs, so they should last you to 60,000 - 80,000 km's, depending on the driving situation.
I have a 2002 Sedona and I agree that removing the inlet manifold is the easiest method to remove the 3 back plugs. It looks imtimidating at first but they are easy to remove with easy access. No need to lift car up, or crawl underneath the car. Once you remove the manifold, just remember to cover the inlet with a large towel of some sort to prevent dirt, plugs, nuts... to fall in

For a Sedona, this is is only useful for the front spark plugs.
I will try to post my pics of my spark plug change soon. But I removed the intake manifold, but not the throttle linkages, when everything was unbolted, I was able to lift and flip the intake upside down and moved to the side to gain access to the rear plugs. It took about 3 hours, but the next time should be faster. I took pics, and will post soon.
Here are 4 main pictures when removing spark plugs in my '04 Sedona.
When the plastic engine cover is removed, the front three plugs are underneath the 3 ignition coil packs.
After taking off all of the bolts and tubes and brackets, you can swing the intake to the side. the throttle linkage is still attached.
The hardest part is removing the rear fasteners of the intake. I used a mirror to find the bolts. You will have to feel around, but it can be done.
The rear spark plug boots are connect to the front coils. Plug straight up to remove without breakage. It is pretty hard if they have not been touched for a while.
