Filter Element 14 x 3-1/16

The K AND N ENGINEERING Filter Element 14 x 3-1/16 (MPN E-3743) is a premium reusable air filter engineered for performance-focused vehicle builders and mechanics seeking sustained airflow and filtration efficiency. This 14-inch diameter, 3.063-inch tall cotton element delivers the core advantage K AND N filters are known for: washable, long-service-life filtration that reduces replacement costs while maintaining or improving intake flow compared to restrictive OEM paper elements.

Constructed from premium oiled cotton media, this filter element is designed for universal fitment applications where a 14-inch diameter housing accommodates the 3-1/16-inch depth. The reusable cotton construction allows multiple cleaning cycles—typically 50,000+ miles between service intervals with proper maintenance—before replacement becomes necessary. Weight at 2.65 lbs positions this as a lightweight option for intake systems sensitive to inertial mass. Unlike disposable paper filters that degrade performance as they accumulate dust, this element's open-weave cotton design maintains consistent airflow characteristics across its service life, translating to more predictable engine response during acceleration and load changes.

This filter suits builders upgrading intake systems on vehicles where increased airflow is a priority—modified engines, naturally aspirated performance builds, and applications running higher fuel mapping benefit from reduced restriction. The 14-inch diameter is commonly found in custom intake plenums, high-flow applications, and non-OEM filtration housings. The red finish is characteristic of K AND N's branded elements and provides easy visual identification during routine maintenance checks. Mechanics and enthusiasts who service their own vehicles appreciate the washability: a simple cleanse with compressed air or light solvent restores filtration capacity without purchasing replacements, lowering ownership cost over 100,000-mile intervals.
