I spoke with AEV. They said lifting and installing larger tires can effectively increase the water depth that the truck can traverse. However, they did stress that the depth is for slowly crossing the deep water. The new depth rating is factory specs or factory number + lift increase + half a tire size increase will give you the new depth limit. However, if going deeper the snorkel will provide plenty of dry fresh air for the engine but other things like electronics, axles, transmission, etc will need to be protected from water for deeper than recommended water crossings.
In dry or dusty areas like the Southwest, dust is actually a bigger hazard to your air intake than water or at the very least a more persistent issue. Dusty conditions can wreak havoc on your air filter, choking your engine and reducing performance. This is why the Snorkel has an optional Pre-Filter. Pre-Filter’s are commonly used on military and heavy equipment, and AEV’s Snorkel now offers you the same protection. They function much like a cyclonic vacuum cleaner, spinning the majority of dust and debris out of the air before it ever hits your air filter.
