Filter Air Kart Asphalt 2.437in Inlet 4in Red

The Filter Air Kart Asphalt 2.437in Inlet 4in Red is a precision replacement air filter element designed for high-performance asphalt kart engines where consistent airflow and contaminant removal are mission-critical. Built for competitors and recreational drivers who demand reliable filtration during extended track sessions, this filter maintains engine cleanliness and throttle response in environments where dust, debris, and fuel residue accumulate rapidly. OTR FILTERS engineered this component to sustain performance across variable track conditions without sacrificing engine longevity or power output.

Measuring 7.3 x 5.6 x 7.4 inches with a 2.437-inch inlet diameter and 4-inch height, this round filter element combines paper media construction with integrated wire mesh support to prevent collapse under high air velocity and load cycling. The red end cap provides visual identification and facilitates quick installation verification in tight engine bay configurations. At 0.85 pounds, the lightweight assembly minimizes rotational inertia while the paper filtration media captures micron-level particles that would otherwise degrade ring seal integrity and piston wall finish over repeated heat cycles.

Kart racers, engine builders, and powersports technicians rely on OTR FILTERS replacement elements for scheduled maintenance intervals when original equipment filters show saturation or performance degradation. The Filter Air Kart Asphalt 2.437in Inlet 4in Red suits replacement applications where OEM specifications call for this exact inlet diameter and height—verify your engine documentation or consult your kart manufacturer's service manual before ordering. Installation requires no special tools; simply remove the retaining collar, slide out the spent element, and seat the new filter with the red end cap facing outward for secure fitment and optimal sealing.
