A cowl snorkel is just what it sounds like. It’s simply an air intake that comes up through your cowl (the spot just back from the hood) instead of sucking air from in the engine bay like a regular intake. This brings your air intake up higher allowing for deeper water crossings. There is definite advantages to this, but please remember that your air intake is not the only thing that can take on water. You also need to worry about your breather lines, etc.. but that is another write-up for another time. You also may want to consider that water splashing up the hood from entering a water hole may enter more readily with this setup, but that’s just an opinion of mine, not fact. Either way, having the air intake up higher can’t be a bad thing for sure.
