As mentioned earlier this is not a snorkel but a Raised Air Intake mainly for dusty conditions (Standard Air Intake is close to the front wheel). Because of the design of the Air Intake system inside of the Fender you would need to go for a long distance at 1000mm height of water to start to get water ingress in the Engine , the vehicle has a reccommended Wading depth of 800mm . I am sure the aftermarket will find a solution and produce a Snorkel, alternatively you could add further fixings to the RAI/Fender to create something more robust and seal all the entry points using some kind of flexible sealant. A full blown Snorkel was not a business case for Ineos at the time and it was decided to focus on a RAI . How do I know.............I am the Lead Engineer for Exterior inside Ineos and this is my design.
