SNORKELS

A vehicle snorkel helps your car to “breathe” when wading through bodies of water. It works in much the same way as snorkels for humans, by taking in clean air from above the water, and preventing water from making its way into the engine, to maintain optimal air flow and temperature

Does a snorkel affect performance?

Purchasing a snorkel ought to improve your car's performance at most engine speeds. Furthermore, it should reduce fuel consumption and make your engine run cleaner. Not all snorkel body designs produce a cold air induction effect. This effect improves fuel efficiency while also improving engine power.

Does a snorkel help performance

A car's snorkel acts pretty much just like the snorkel you'd use during an island vacation—it raises the point of entry for air higher and away from water. Just like your own lungs, your car's engine can't breath while it's submerged... that and the catastrophic failure that water entering it can cause.
