Engine Air Intake Filter Element for Smooth, Efficient Infiniti Power

This direct-fit intake element keeps your engine breathing clean, steady air. It blocks dust, sand, and pollen before they reach the mass airflow sensor and cylinders, preserving torque, MPG, and throttle response. Built with multi-layer synthetic media and precise pleat geometry, it traps ultra-fine particles while keeping airflow strong. The molded polyurethane rim seals tightly in the airbox—no leaks, no bypass, no drama.

Why you need it ✅

Fresh filtration protects rings, bearings, and the MAF, and helps the catalytic converter live longer. Replace every 12–15k miles (sooner in dusty or urban stop‑go). A clean element can restore smooth idle, reduce intake roar, and stabilize fuel trims for better driveability.

How it works ️

Incoming air passes through a prefilter layer, then through electrostatically charged fibers that capture micro debris. Large surface area lowers restriction, feeding the MAF a steady, laminar stream. The perimeter gasket maintains an airtight seal even under heat soak and vibration.

When the filter is bad or damaged ⚠️

Expect lazy throttle, higher fuel use, whistle on load, and possible CEL (P0101, P0171/P0174). Clogging starves the engine; tears allow grit to score cylinders and turbos. Oil-fouled or warped media can contaminate the MAF, misfire, and blacken plugs.
