Toyota Repair: Spark plugs on 2002 Sienna, plenum chamber, universal joint

Question
I have a 2002 Sienna and I want to replace the spark plugs. I can see the three front plugs. My question is how do I get to the three other plugs on the other side of the engine.Thanks for any assitance.

Answer
You can remove the wires by reaching behind the plenum chamber from the right you can reach #3+5, from the left you can get to the #1, after the connectors are removed you can access the spark plugs with a socket and a couple of extensions(a 2" and a 6" and a universal joint and a ratchet, it's basically trial and error to find the right combination of extensions that will reach up high enough to get the ratchet on it to remove the spark plug, this is not an easy task.
