Filter Air Kart Asphalt 2.437in Inlet 5in Black

The Filter Air Kart Asphalt 2.437in Inlet 5in Black from OTR FILTERS is purpose-built for go-kart and small-displacement engine enthusiasts who demand reliable intake filtration without sacrificing airflow. Whether you're prepping a race kart for competitive asphalt events or upgrading a recreational machine, this filter delivers consistent performance in high-demand applications. Designed with a 2.437-inch inlet diameter, it integrates seamlessly into kart-specific intake manifold architectures where precision fitment matters.

This air filter features a 5-inch overall diameter and engineered filtration media that balances restrictive efficiency with volume flow rate—critical for maintaining peak torque delivery in tightly-tuned small engines. The black finish resists UV degradation and maintains appearance through repeated washings, while the compact 7.4 x 5.5 x 7.4-inch profile fits tight engine bay layouts common in kart construction. OTR FILTERS construction prioritizes durability; the filter media is rated to handle dust ingestion without fouling spark plugs or restricting fuel mixture—a common failure point in under-spec'd intake systems.

Kart mechanics and weekend racers benefit most from this direct-fit solution, as OTR FILTERS engineering ensures compatibility with standard kart carburetor and manifold combinations across Briggs & Stratton, Honda GX, and comparable small-displacement platforms. Installation requires no adapter rings or custom ducting—simply secure the inlet at the specified 2.437-inch diameter and the filter seats positively. Weighing just 0.95 lbs, it adds minimal rotating mass while delivering the filtration performance necessary for sustained high-RPM operation on asphalt courses.
