A snorkel installation kit includes a fender pipe and a snorkel. The fender pipe has an air intake. The snorkel has a protrusion defining an outlet that is received by the air intake of the fender pipe. The fender pipe and the snorkel are separated by a space when installed to each other.

A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, and a plurality of body panels supported by the frame. The utility vehicle also includes a radiator supported on a rear portion of the frame. Additionally, the utility vehicle includes an air intake assembly partially supported by an upper portion of the frame.

The presently disclosed subject matter is generally directed to a system and method of protecting the engines of ATVs by preventing excessive water from entering the belt drive and/or air intake of the vehicle motor. The system includes a riser and valve assembly. Each snorkel valve assembly includes one or more water sensors in communication with a valve. When water is detected by the sensors, the valve closes, preventing water from entering the vehicle engine, transmission, air box, clutch housing, and/or any other vented element of the ATV engine. Instead, the water is diverted out of the system through a drain valve. Accordingly, the system prevents water, mud, and the like from entering the main components of the ATV motor.

A vertically extending air intake duct on a rear of a cab in a delivery vehicle to take in ambient air for an engine through an air intake has a duct body as an outer shell with the air intake on an upper portion; a side branch section on a lower portion of the body and having upper and lower ends opened in the body and outside, respectively; a mesh member extending over the air intake to collect rainwater; a louver for covering the mesh member and the air intake to prevent intrusion of matter other than ambient air; and a drip channel or bead on an inner wall of the duct body and just below the mesh member to capture and guide rainwater flowing down on the inner wall to the upper end of the side branch section.

An intake port may include a short port and a long port. The short port may include a main extension portion extending from an intake air inlet; a main inclined portion inclined at a predetermined angle from the main extension portion toward a center of a cylinder; a main vertical portion bending downward toward the cylinder from the main inclined portion; and a main intake air outlet formed at an end portion of the main vertical portion. The long port may include an auxiliary extension portion extending from the main extension portion; an auxiliary inclined portion which is inclined at a predetermined angle from the auxiliary extension portion toward the center of the cylinder and inclined at a predetermined angle downward toward the cylinder; an auxiliary vertical portion bending downward from the auxiliary inclined portion; and an auxiliary intake air outlet at an end portion of the auxiliary vertical portion.

The disclosure relates to an air filter assembly for cleaning an air stream for a commercial vehicle, including a pre-filter communicating with an air intake and a first fine filter which is provided downstream of the pre-filter in the direction of the air stream and, together with the pre-filter, is associated with an air filter part which extends vertically in a predetermined installation position. A redundant second fine filter, which is associated with an air filter part which extends horizontally in the predetermined installation position, follows the first fine filter in the direction of the air stream, the horizontally extending air filter part being a component of a syphon-like conduit region which rises in a curved manner in the direction of an air outlet, starting from the redundant second fine filter.
