You can also adjust the height of the cone filter as needed. I live in a very dry climate so I have a completely exposed filter, if it rains where you live, feel free to tuck the filter up behind the bumper.

OEM Air Snorkel acts as a siphon break. You cannot develop a vacuum deep enough to pull water up the cone filter suction hose unless the OEM airflow path becomes completely obstructed.
