DryFlow Air Filter 3.25in X 5-1/4in

The DryFlow Air Filter 3.25in X 5-1/4in by AEM INDUCTION delivers efficient engine air intake for automotive enthusiasts and performance builders seeking improved airflow without the maintenance burden of traditional oiled filters. Engineered for universal fitment with a clamp-on conical design, this synthetic air filter element suits custom intake builds, engine swaps, and retrofit applications where standard factory air boxes are replaced. The DryFlow technology provides reliable filtration while maintaining engine longevity across a wide range of driving conditions.

This conical air filter element features a 6-inch base diameter tapering to a 5-1/8-inch top diameter, with a total height of 5-1/4 inches and a 3-1/4-inch mounting flange for secure clamping integration. The synthetic media construction eliminates the need for re-oiling, reducing maintenance frequency and providing consistent filtration performance throughout extended service intervals. The red filter media is optimized for dry-flow operation, allowing superior engine breathing while capturing contaminants without sacrificing air velocity—critical for naturally aspirated and boosted applications alike.

Builders and tuners benefit most from the DryFlow Air Filter when constructing custom intake manifolds or upgrading existing air induction systems where OEM restrictions limit performance potential. Installation requires only a compatible clamp-on intake tube sized to the 3-1/4-inch flange; no special tools or adhesives are necessary. The universal design accommodates a wide variety of engine platforms, making it an ideal choice for street performance, off-road, and motorsport applications where reliable, low-maintenance air filtration is essential.
