Paper Air Filter 14x3 Flows 1000+ CFM Asphalt

The WIX RACING FILTERS Paper Air Filter 14x3 Flows 1000+ CFM Asphalt (Model 46945R) is a high-flow intake element engineered for applications requiring sustained airflow capacity and engine protection in asphalt-based or dusty environments. This 14-inch diameter round filter with 3-inch height delivers 1000+ CFM performance, making it suitable for high-horsepower builds and applications where intake volume demands exceed standard filter capacity.

The white paper construction provides reliable particulate filtration while maintaining the airflow characteristics necessary for performance-oriented engines. WIX Racing Filters are manufactured to tight tolerances and deliver consistent micron-level filtration without unnecessary restriction. The 14.5 x 4.35 x 14.75-inch mounting envelope accommodates standard round filter housings commonly found in race-prepared and heavily modified engine builds. Paper element filters require periodic replacement—typically after 10,000 to 15,000 miles of driving depending on operating conditions and air quality.

This filter is specified for builders and operators running high-displacement or turbocharged engines where intake demand exceeds factory filter capacity. Applications include custom automotive builds, off-road performance vehicles, marine engines, and industrial equipment requiring sustained high-volume air intake. The 1000+ CFM rating ensures minimal restriction even under peak load conditions, supporting both naturally aspirated and forced-induction configurations. Users should verify housing compatibility and sealing surface condition before installation to ensure proper filtration and prevent bypass.

WIX Racing Filters occupy a recognized position in the performance filtration market, used by engine builders and racing teams where filter quality directly impacts engine longevity and power output. High-flow paper elements balance maximum airflow with effective particle capture—a critical tradeoff in performance applications where both air restriction and internal engine wear must be minimized.
