Open Funnel Performance Air Filter 3In Inlet ID

The VIBRANT PERFORMANCE Open Funnel Performance Air Filter with 3-inch inlet ID is a clamp-on conical air filter element designed for high-flow intake systems on vehicles requiring enhanced airflow and filtration. This universal cotton filter combines open-funnel design principles with practical clamping installation to deliver increased intake velocity while maintaining effective particulate capture across diverse operating conditions.

Constructed with premium cotton media, the filter features a conical geometry with a 6.5-inch base and 5-inch top diameter, standing 5 inches tall. The 3-inch flange accommodates standard intake ducting and clamp-style mounting hardware for secure, repeatable installation. Cotton media filters offer superior flow characteristics compared to paper elements while providing effective filtration of intake air—a critical balance for performance applications where both horsepower and engine longevity matter. The blue media coloring aids visual condition assessment during maintenance intervals, helping operators identify saturation and schedule cleaning or replacement before performance degradation occurs.

This filter suits applications ranging from light-duty off-road vehicles and recreational trucks to performance-oriented street builds where increased intake volume supports modified engine tuning. The universal design accommodates custom intake manifold configurations and aftermarket intake systems that leverage larger-diameter ducting. Operators commonly pair open funnel filters with upgraded intake manifolds and tuned fuel maps to extract marginal performance gains while maintaining reliable cold-start and part-throttle drivability. The lightweight construction (1.15 lbs) minimizes rotating mass in the intake tract, reducing parasitic load on the engine's intake valve actuation.
