Want to change the spark plugs on my 2003 Toyota Highlander 3.0, 43,000 miles. Front plugs are easy to access, but rear plugs seem like a bear to get at (can't even see them. Alldata says 2.8 hrs. for plug change, but they give no specifics or step by step. Based on 2.8 hr labor time, I can only assume that the intake plenum needs to come off. Can anyone verify this or are there any shortcuts. Truck runs fine, but I think after 5 years they should be changed. Thanks in advance for any advice. My best to all for a happy and safe holiday.
