Snorkels are for more than just deep water crossings. Snorkels help ensure water does not make its way through your airbox and into your engine while crossing rivers and unexpected floodways. The fitment of a well designed and constructed snorkel, just as importantly, protects your engine from dust while traveling along dry dirt roads. The fitment of a snorkel repositions the air-intake to a much higher and cleaner location, significantly reducing the amount of dust passing through to your airbox and filter.
