Hello I was just wondering if anybody has changed out their spark plugs by themselves on a 2007 V6 Veracruz? I know the dealer wants $350 and that seems outrageous for six spark plugs . Also has anybody ever replaced a mirror assembly on this same vehicle? Do you have to take the whole door panel off? I appreciate any input or advice for these two projects.

 

Do you want to know why changing the spark plugs are so expensive? Because to even access the rear 3 plugs, you have to remove the upper intake manifold.
Here's a good video of what's involved (different car, same basic engine and procedure):
