Does anyone have or know of a deailed expanation of how to successfully remove the Air intake to change the rear spark plugs on the 1MZ highlander engine? I would like to change it myself and save $300 but am not sure how to with the information contained in the threads.

Also are there any gaskets that should also be replaced when the intake is off?

You don,t have to take it off you need the right tools to get around and under it. It is difficult but that is the way we do it. Use 1/4" hand tools to take the coils off and a 3/8" to remove the plugs. Let it cool down. 300 is way to much to pay for a tune up.I think ours are 150 or so.
