It doesn’t need to be air and water tight imho. The car isn’t otherwise hermetically sealed. Not a whole lot of water flows down the firewall imho. Wouldn’t take much to make it more water tight if it’s something that causes you to lose sleep. No firewall grommet on convoluted tubing is likely watertight.
Just my two cents,
