Filter Air Kart Asphalt 2.437in Inlet 5in Blue

The Filter Air Kart Asphalt 2.437in Inlet 5in Blue by OTR FILTERS is a high-performance air intake filter engineered for competitive kart racing and motorsport applications where engine breathing directly impacts lap times. This filter is designed for operators who understand that intake filtration is critical to maintaining peak horsepower output while protecting against airborne contaminants that degrade engine longevity. Built to specification for precision kart engines, this blue filter assembly integrates seamlessly into asphalt track setups where consistent performance and reliability are non-negotiable.

The 2.437-inch inlet diameter is precisely engineered to match OEM or performance kart manifold specifications, ensuring optimal volumetric efficiency without restriction or turbulence. The 5-inch filter element provides substantial surface area for extended service intervals while maintaining low pressure drop across the intake path—a critical factor in two-stroke and four-stroke kart powerplants where every fraction of a horsepower counts. OTR FILTERS construction utilizes durable, high-flow media that balances micron-level filtration with minimal air resistance, protecting combustion chambers from abrasive particles while preserving the throttle response that competitive racing demands.

Racers and kart technicians seeking to maintain stock or mildly modified engine performance on asphalt circuits will find this blue filter element compatible with both stock intake manifolds and entry-level performance modifications. The compact 7.4 x 5.6 x 7.5-inch profile fits standard airbox enclosures without requiring extensive re-fabrication, making installation straightforward for pit crews preparing equipment between events. At 0.9 pounds, the lightweight assembly contributes minimal parasitic load to the engine bay while the blue finish aids in quick visual inspection for contamination or clogging during routine maintenance checks.
