I can't seem to find any install literature on Crawford AOS for the 2019 STi. Is your AOS kit specifically made for your model year? My expertise is with the GD chassis, but I might be able to help if you post some pictures of the kit and engine bay. I can't imagine the bay being THAT MUCH different from 04-19, considering it's still an EJ257. :unsure:

Haven't done it on a '19, but since the kit is for a '15-'19 my guess is that there are extras included to account for differences between model years.

A lot of times you can't re-use the stock clamps, but they should have included some in the kit. Looking at the pictures online, it looks like maybe thats what all the zip-ties are for?
 
I know this is a couple months old and your project is likely done but wanted to close the loop. I installed the IAG AOS last weekend, haven't posted on my build thread yet but plan to soon.

Several low pressure clamps were reused. Saying that, they were never removed from the hose, just pull the hose off with clamp in place then push back in place leaving the clamp. All new low pressure hoses used zip ties. The two high pressure lines came with new clamps.

Hope this helps someone in the future who may run across this thread.
