Picture your Wrangler at the end of a convoy on a dry dusty trail. As each vehicle before you stirs up dust and debris, your air filter is forced to contain the contaminants as your engine gasps for air. Now picture your vehicle entering a water hole. As the front tires leave the embankment and your Jeep noses into the water, the air intake becomes incredibly vulnerable to water ingestion. Taking water into your engines combustion chambers will create what's known as "hydro lock".
Modifications to the stock air box are needed to use this kit with Air Conditioning.
