What is the purpose of a snorkel?

[DiJasper]

Installing a snorkel significantly raises the position of the engine's air intake, ensuring that the engine does not suck in water when the off-road vehicle is wading, which helps the engine work and allows for more efficient air intake. Here is some extended information: 1. The more official term for a snorkel: It is called a "high-position intake pipe" or "wading device," and to put it plainly, it is an extended intake pipe. The real purpose of a snorkel is to assist the engine in working, allowing it to breathe fresh air and gain more power. Therefore, wading is just a side effect of the "snorkel." 2. Waterproof measures: If a car wants to traverse relatively deep water, installing a snorkel is only one aspect. It is also necessary to remove all electronic equipment on the dashboard, such as navigation systems, CD players, etc., and then reinforce waterproof measures for all lighting fixtures.
