Well, the hilarious thing is the one I lost is off Bay 2 (driver side).
I will post the sizing for the replacement because some thread in this forum said M6-1.00 x20mm would fit and it's too skinny. I picked up a few boxes of flange bolts around this size and I'll give an update on what fits. I'm going to be going to the dealer again anyway because -
I installed the other 3
spark plugs. Rain was forecast and I was determined to get it done before (I don't have a garage or any overhead covering where I am). The intake side was a pain, but doable. I managed to keep the coil packs mostly intact. It's the pack that sits right under the charge pipe area that was the worst. My fingers couldn't fit well underneath and still get leverage so I used spark plug pliers to help in the tight spaces. Fired the engine up after and gave it a few 3k~RPM revs, no misfiring. I planned on a short drive to confirm no CEL and normal operation and of course - TPMS light went on. One of my tires seems to have a slow leak, despite being fine the night before. FML, of course! I got the tires rotated at the dealer earlier this week when I had them do the 12k mile inspection. I didn't find any obvious puncture. I brought it to Tire Warehouse and learned something new - apparently you can't change just one tire on a AWD vehicle. (Pretty embarrassing to learn that fact as I did lol) I asked them if they could at least see if it was a flat and go the repair route there just to tide me over and they also refused. So the JB4 install will have to wait a day while I go back to the dealer to get new tires ( I anticipate they will have OEM in stock). Thing is, the other tires still have good tread on them... what will I even do with them? Can't imagine anyone will want to buy them. Maybe they will be sand baths for my chickens.
I have one more actual day off with nothing planned so we'll see if I can't get the JB4 in tomorrow and give that a go. So close... the saga continues!
