I agree... the FJ's intake was not placed at the best location...so you have to be careful...It all depends on the intake location. The higher the vehicle the less chance for it to pick up water
Ahh! Not saying it's impossible, just improbable. The other "SUV" are not any better (in general).Toyota states the FJC was designed for water fording up to 27.5" deep out of the box. if you want to go deeper consider an ARB snorkel. You should also consider the FJ Cruiser Scuba Mod which raises the rear differential breather since it sits lower than your air intake and can suck water in under the right circumstances.
As said earlier this does not mean rushing in and making a big splash but rather keeping steady momentum that maintains a bow wave ahead of the rig.
