This may be somewhere else on the forum, but thought I'd share in case anyone finds themselves in the same predicament as I did.
When I removed the Brake Booster Cover on my 2018 Genesis G80 3.3T to install by JB4, I broke a couple of the Cowel clips. I searched to try to find the parts online. I couldn't so I ended up buying 5 from the dealer. They were $4.50/piece. When I got the packaging I got the part number. 86155 2H100.
Online you can get 15 for $15 bucks. See the link below.
