Hello, I need some advice about what tools I need to reach the back spark plugs of a 2007 DTS.I changed the front with no problem, but the 5/8 spark plug extension socket I was using is too long to. The hood gets in the way. This is my first time changing the spark plugs on my DTS. Has anyone change their spark plugs on a 2006 or 2007 dts?
