Air Filter Element Red 14in x 3in

The Edelbrock Air Filter Element Red 14in x 3in (Part Number 43666) is a replacement cotton-media air filter designed for high-flow engine induction systems. This round, 14-inch diameter filter element delivers superior air volume and filtration for carbureted and fuel-injected engines requiring universal-fit circular filter housings. The distinctive red finish aids in quick visual identification during maintenance routines, making it a practical choice for shop inventory and field applications where filter condition monitoring is critical.

Constructed from high-quality cotton media, this air filter element provides excellent filtration efficiency while maintaining the low-restriction airflow characteristics essential for performance-oriented engine tuning. The 3-inch height balances compact packaging with adequate dirt-holding capacity, extending service intervals compared to thinner elements. The media composition and pleat design optimize dust separation without sacrificing volumetric air delivery—a critical factor in maintaining proper air-fuel mixture and fuel economy across varying throttle conditions and load states. Weighing 1.78 lbs and measuring 14.7 x 3.5 x 14.7 inches in the housing, the element fits standard pro-flow filter assemblies used across automotive applications.

This replacement element serves technicians, engine builders, and vehicle operators maintaining carbureted or fuel-injected engines with circular induction housings. Regular replacement of air filter elements—typically every 15,000 to 25,000 miles depending on driving environment—protects engine internals from abrasive particulate and sustains optimal performance. The universal fitment makes the 43666 a reliable spare part for shops stocking multiple vehicle platforms, reducing lead times when filter replacement becomes necessary during scheduled maintenance or pre-event vehicle prep.
