I came here to ask about your front tow shackles because I didn't see them in the build list anywhere.

RE:Spark plugs...
I had a 2013 Focus ST, I tuned it hot and did a bunch of mods at around 30K. At 60K I figure it was time to change plugs (people on the forums were complaining about misfires and showing bad, worn out plugs). This was around late 2014 or so, so the 2015's were out. The plugs I ordered were OEM (Sp534 plugs I believe). The ones that came out of my car were pristine, and could have gone another 60K easily. I ended up changing them out because I had them in hand...
At 90K I checked them again and they were ate to crap. The Gap was like 50 thousandths and the ground was severely pitted. Turns out the factory plugs on the 2013 were awesome, and there was a mid year "refresh" in 2014 where they just changed the quality of the materials making the plugs last less than half as long.
They all had the same part numbers too...
