Performance Air Filters and Replacement Filters This collection covers filtration for factory air boxes, aftermarket intake systems, custom intake tubing, crankcase ventilation and vehicle HVAC systems.

Similar-looking filters are not automatically interchangeable. Choose the Correct Air Filter Type Direct-fit and drop-in filters: shaped for a specific factory air box or listed intake system. Universal clamp-on filters: selected by flange inside diameter, base and top dimensions, height and available clearance. Cabin and HVAC filters: vehicle-specific filters for air entering the passenger compartment. Breather filters: compact filters for compatible valve-cover, crankcase-vent and catch-can applications. Pre-filters and wraps: outer covers designed for compatible primary filters in dusty, sandy or wet environments. Velocity...

Shop universal air filters for custom intake tubes, turbo inlets, carburetors, velocity stacks, crankcase breathers, and fabricated performance systems. Compare clamp-on cone filters, open-funnel designs, oval and tapered filters, carbureted air-cleaner assemblies, reusable oiled media, and dry synthetic options. Universal fitment depends on exact measurements, available space, mounting orientation, and the intended airflow path—not year, make, and model alone. Universal Air Filters for Custom Intake Builds A universal filter is selected by dimensions and interface. The flange inside diameter must match the intake tube, turbo inlet, velocity stack, carburetor neck, or breather connection. The filter body must also clear nearby panels, wiring, hoses, heat shields, suspension components, and the hood while leaving enough exposed media for the application. Measure the installation area before ordering. Record the flange size, base width, top width, overall height, filter shape, mounti...
