I just did mine. 2013 V6 with 88k miles. Took about 4 hours........It is NOT for the squeemish.......there are a few parts that are absolutley CONFOUNDING to reassemble. It was great to know that I had done what I could, since 1,100 was quoted and the part was only 125.00 and in the end I was able to clean the valves, etc., But my problem did not go away. So at least I only burned 125...........that said if you have a mechanic friend to help think through things it would be very helpful...since much of the work involves thinking ahead and being somewhat creative.........
