The Mantec Snorkels were legendary Camel Trophy Discos,
as well as other Land Rover Special Vehicles Discos like the G4 Challenge Discoveries. The Camel Trophy Defenders and G4 Challenge Freelanders were also fitted with Mantec Snorkels.
The snorkel raises the air intake from under the hood to the roof line. When wading, the snorkel prevents water intake into the engine. Even on a petrol engine (most of which are not waterproof and will not run submerged), the snorkel prevents hydrolocking the engine. Even if your petrol engine gets wet and stalls, you can still get pulled out of the water and restart. You cannot repair a hydrolocked engine in the field.
Even if you never venture into water, the snorkel also lets the engine breathe cleaner air because the air high outside the vehicle is generally cleaner than the air under the hood. A snorkel is especially welcome on the Disco2, which has its air intake located inside the front wing beside the wheel well.
On longer trips, it is not uncommon to find the air filter clogged because of dusty conditions. Driving behind others in a convoy on a dirt road is very dirty.
An field-expedient fix is to blow the filter clean with onboard air. Some conditions are so dusty that even with a raised air intake you will have to do this to keep your vehicle running. But a snorkel definitely helps.
Unlike other snorkels, the Mantec Discovery Snorkels parallel the vehicle's A-pillar and provides a very factory appearance. The snorkel is hidden from view from the driver's seat and the driver's view of the road ahead remains unobstructed.
