It says to not use on Karman Vortex Air Flow Sensors and mentions some lexus vehicles. We can use it on the GX right?

yes the GX is hotwire type maf its safe to use generally speaking.

The only Lexus cars that I am sure of were the 90-94 LS400s. There could easily be others of that vintage that used the Karman Vortex AFM.

yeah the 92-95 sc400's and sc300's have them as well. mk3 7mgte supra's also had them. thats most of the important ones off the top of my head.

it boils down to this, if your maf is black plastic, its ok to use.
if your maf is a metal looking rectangular box with a mesh grill on the front, dont even leave it in the same room as the crc cleaner.
