Next remove the backing plate for the air filter, 3 torx bits inside, and 2 hex heads above the throttlebody to the left and the right, these two thread into the heads. There are also 2 o rings behind these. I had one stick to the head until I removed the rocker box cover, then saw an oring fall and roll away. Luckily I hadn't removed the cover yet, so the engine hadn't been opened so it was easy to figure out where it came from.
