2015 spark plug replacement on driver side access
How do I access the driver side to replace the spark plugs? ? Do I got to pull this big black cover off as seen in the picture? Can somebody walk me through it? Passenger sides a piece of cake

Even with the ECU removed, it's still a tight space to work in. But doing it this way you don't have to remove the intake plenum.
Disconnect ECU, disconnect vaccum line, use a string/thin rope to grab unto the coil to pull it out like in the PDF document.
You may have to take the intake manifold off (the big plastic thing) to get more access (that's what I did). If you remove manifold be careful with vacuum lines in the back and the runner gaskets.Good luck.
