Terrafirma - Plastic Raised Air Intake - LH

A critical yet often overlooked enhancement for any serious off-road vehicle. While snorkels frequently top modification lists, raised transmission breather kits deserve equal priority. Deep water crossings requiring snorkel protection are far less common than 18" submersion events that can necessitate expensive differential rebuilds. Vehicle gearboxes and fluid reservoirs naturally expand and contract during operation, requiring breathers to function properly. When a hot axle suddenly contacts cold water, thermal contraction causes the axle casing to draw in air. If submerged, this action will pull water past the seals—which are designed to retain oil rather than exclude water. The resulting water contamination rapidly degrades seals, bearings and gears, leading to premature failure. Vehicles subject to deeper submersion benefit significantly from extended breather lines routed to the vehicle's highest point, typically a raised air intake. Terrafirma provides comprehensive breather kits addressing all major components including front and rear axles, gearbox, transfer box and timing case. While raised transmission breathers substantially reduce water ingress risk, they cannot guarantee complete protection during persistent deep-water use and should not be considered a complete waterproofing solution. Extended breather kits represent one of the most valuable off-road investments available. Note: A raised air intake alone does not make your vehicle amphibious; comprehensive additional modifications are necessary to achieve full waterproofing capability.
