^^^ This. The 6L is a superior transmission IMHO, and I wouldn't want to "change" the 6L80 to an 8L80 regardless of possibility or cost. If the 6L failed, get it fixed or replaced with the same.
Seriously thinking of a PIAA light mount #30765 and one or two pairs of PIAA 520 series lamps on it. The factory "fog" lamps on my 2018 are nothing more than accent lighting.
