Air Filter Round 14 x 3

The GREEN FILTER Air Filter Round 14 x 3 (MPN 2012) is a reusable high-flow intake solution designed for automotive enthusiasts and mechanics seeking measurable gains in engine breathing and filtration efficiency. This round 14-inch diameter design provides a larger effective filtering surface area, making it ideal for street machines, performance builds, and daily drivers where intake temperatures and engine response matter.

The reusable construction reduces long-term maintenance costs while delivering consistent airflow characteristics across extended service intervals. GREEN FILTER's washable foam or cotton blend media is engineered to balance filtration density with unrestricted airflow—a critical balance that directly impacts volumetric efficiency and throttle response. The 14-inch diameter body with a height of 14.35 inches fits compact engine bays while maintaining sufficient media volume to handle sustained high-RPM operation without pressure drop penalties.

The reusable design means you clean and re-oil the filter element according to maintenance intervals, restoring filtration capacity without replacing components—a cost-effective approach favored by serious modifiers who log significant seat time and demand repeatable performance metrics. This air filter rounds out builds where intake manifold modifications, carbureted conversions, or custom air box fabrication demands versatility and reliability.
