I would like to know the wire spark plugs arraignment on a Kia Sedona 2004 3.5 motor LX

SOURCE: 2004 kia sedona 6 cly ... how to change the spark plugs anyone???

Hope not too late to help. I have changed all plugs 2 times now myself. Mine is a 6 cylinder. The rear 3 plugs are impossible to remove without unbolting the intake manifold and other contraptions like the throttle/cruise control cable and 4 inch air intake tube. If you have engine work experience, great! If not, color code every disconnect then match up on the reinstall including plug cables.
Here is where you might not know what to do. First, the gasket (Planum) is a reusable metal gasket. Their is no replacement at Kia (crazy but I asked everywhere in NC) so be sure to tighten each bolt on the intake alternating and to speck amount, a 12 foot socket 1/4 inch wrench is plenty of torque so don't overdo it. I believe 15 lbs of torque is correct but verify. If you like taking risks just tighten using your wrist only (not biceps mustle) as tight as you can using wrist only now! [Rent a torque wrench or buy for $10 - $20 if you don't own one].
Since your doing all this work, change all plug wires and only use Platinum or better plugs that last at least 60k miles of use. You wont be able to change back 3 wires later by the way so buy 3 OEM Kia wires (not the kit) to save money if you want. I mixed plugg types and mine ran just fine!!

Plan on 4 meticulous hours your first time. My 2nd time took 1.5 hrs with a short break.

REMOVAL OF THE PLUGS:

Do not attempt any maintenance on spark plug if engine is hot. 
1. Disconnect negative battery terminal. 
2. Carefully remove high-tension leads. 
3. Use compressed air to blow any dirt or debris from around spark plug hole. 
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.

Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug. 

INSTALLATION:

1. Install spark plug into cylinder head.

Tightening torque : 18~22lb-ft (25~30N·m, 2.5~3.0kg-m)

2. Reconnect high-tension leads. 
3. Reconnect negative battery cable. 

Hope this helps and simple to understand. Good luck

You'll need to remove the upper intake and throttle body. Involves unbolting and unplugging alot of things.
