These snorkels are all new designs, tested on a custom built flow bench, to flow 25% to 70% more air than the stock air cleaner housing flows from the vehicle manufacturer, whilst still providing a watertight raised air intake. The Air Ram is designed to remove the maximum volume of water from the incoming air stream, while delivering the maximum airflow to your vehicle’s engine. By rotating the air ram to face away from the prevailing wind/direction of motion, the air ram delivers additional protection from the elements.
