Wix Engine Air Filter WIX 46116 for Infiniti & Nissan (81–19) — Reinforced Pleats, Heat-Resistant Seals

The WIX 46116 is a high-efficiency engine air filter built with reinforced pleats and pliable seals to keep dust out and support consistent engine performance.

Designed as a direct-replacement air intake filter for a range of Infiniti, Nissan, Saab 9-2X and Subaru vehicles, the WIX 46116 prioritizes contaminant capture, a reliable seal, and durable construction. Its embossed pleat pattern and stabilization beads increase the usable filter area, while heat-resistant plastisol gaskets create a snug fit that helps prevent unfiltered air bypass. This filter is intended for routine maintenance replacement to help protect critical engine components by reducing the amount of airborne dirt and debris entering the intake system.

How does this filter help protect my engine during normal driving?

The WIX 46116 traps airborne particles before they reach intake valves and combustion chambers, reducing abrasive wear on engine parts. Its pleat design increases dust-holding capacity so the filter can perform longer between service intervals.

• Embossed pleats and stabilization beads for higher dirt retention
• Heat-resistant plastisol seals for a consistent gasket contact
• Designed to fit OEM housings for correct airflow path

What makes the WIX 46116 different from basic replacement filters?

Compared with generic elements, this WIX filter emphasizes structural reinforcement and seal quality. The pleat stabilization beads prevent pleat collapse under airflow, while the pliable top and bottom seals maintain a tight barrier to minimize bypass.

• Reinforced pleats maintain shape under load
• Pliant seals adapt to housing irregularities for a reliable fit
• Engineered for consistent airflow and filtration efficiency
