05 Sedona. I know getting to the rear set of three spark plugs is a pain in the neck. Would it be ok just to change the front three? Would this mess anything up or not be recommended/ Thanks in advance!
I don't think it will actually cause any major problems but it would be better to change them all because the back plugs will be in the same condition as your front three are. Isn't it great fun working on some engines where they make servicing so easy?

TAKE YOUR TIME, THINK IT OUT, DO IT RIGHT, DO IT ONCE!! original quote by me as far as I know. ALL MEMBERS PLEASE FILL IN USER PROFILES. DETAILS HELP OTHER MEMBERS HELP YOU .
I knew it would ne expensive thats why I ask about the three. Getting to the back three is hard and the front is easy enough.
Here is a link to the best DIY tutorial I know of explaining spark plug replacement on a transverse mounted Hyundai/Kia Delta or Sigma V6 motor. This example involves a Santa Fe SUV with the 2.7 liter V6.
The 3.5 liter V6 in your Sedona is essentially a bored and stroked version of the 2.7 liter motor. You will no doubt find subtle differences between the two applications, but the fundemental process of loosening the surge tank assembly to get at the back 3 plugs is pretty much the same.
The Sante Fe description is good, but not so fast. Everything up to propping up the intake up is very much the same as the Sedona, but at step 18 - remove rear spark plugs, this deceiving. A small mirror is useful and there are a couple of engine life brackets that must come off to get to the plugs. 45 minutes to get to step 17 is very aggressive, think 1 hour plus on the Sedona. Search for my pictures in the forum gallery - rob_fed. You will find other spark plug removal pictures there of my actual Sedona.
