Is that clear tube coming out of the firewall by the dipstick for the A/C? It looks like bare metal around the hole. You're going to want to paint that or it will rust. A grommet might be a good idea too.
Yep, its AC vent tube. I had to move the hole from the OEM location, for the CAA unit. I already have the grommet for it, its on my "small stuff to do" list. I'm not really a big fan of clear hose, so I'll probably change it to black with a 90 degree bend. Thanks Darren
