Dryflow Air Filter 4x5.25

The AEM Induction Dryflow Air Filter 4x5.25 is a high-performance conical air filtration element designed for engine intake systems requiring efficient airflow and extended service intervals. This synthetic dry-flow filter delivers superior filtration without the need for oil-based coatings, making it ideal for street applications, tuning builds, and performance modifications where consistent air quality is essential to engine longevity and power output.

Engineered with a 6-inch base diameter and 5-1/8-inch top diameter, this filter element measures 5-1/4 inches in height and features a 4-inch clamp-on flange for secure mounting. The conical geometry maximizes surface area for dirt trapping while minimizing restriction, allowing your engine to breathe freely across the RPM range. AEM's synthetic media construction resists moisture and provides reliable performance in diverse environmental conditions—from daily street driving to spirited track sessions. The bright red finish aids in quick visual identification during maintenance intervals.

This universal filter element suits builders and tuners upgrading factory air intake systems or designing custom intake manifolds where OEM filters fall short of performance goals. Whether you're optimizing a naturally aspirated engine for peak efficiency or integrating forced induction, the Dryflow Air Filter 4x5.25 delivers the filtration reliability and airflow characteristics serious builders demand. The dry-media design eliminates oiling maintenance, reducing downtime between service intervals.

AEM Induction is recognized for precision intake engineering and filter technology that balances restriction, durability, and protection. The Dryflow line represents their commitment to synthetic filtration for builders who value simplicity and consistent performance without the complexity of traditional oiled-element care.
