The Fumoto drain valve part number is F108SX. They are well made (in Japan) and make oil changes easier by not needing to keep removing the drain plug. Torque for this particular unit is 18 ft lbs. Check Fumoto's website for more details if you need to: https://www.fumotousa.com/cars-pickup... I've had one of these in my 2014 twin turbo F150 truck and it has 171,000 miles on it now with no issues from the drain valve.

Using a Wix WL10078 for the oil filter replacement (high quality filter)

I have some nice photos of this WRX on my photography website here: https://www.thephotographyhobbyist.co...
I'll add more photos once the red STi under spoilers are installed (no idea when the dealer will be getting them).
