Learn from my experience today.. it appears you need to purchase the extension piece with the F-106 fumoto valve. The Adapter is ADP-106.

Luckily, the oil change kit I got from ECS had their magnetic drain plug. I'll be swapping the fumoto in during my next oil change in 5K.

There is another valve offered, the F106SW that I may try to get instead, to see if it fits. This one has somewhat of an adapter built into it, so it may be just enough to clear the indent in the oil pan.
