High‑Precision Air Flow Meter for Smooth Nissan Performance ⚙️

Keep your engine breathing right with this calibrated mass air flow sensor (MAF). It feeds exact air intake data to the ECU, so fuel delivery and ignition timing stay on point. Expect stable idle, crisp throttle response, better fuel economy, and cleaner emissions—ideal for daily driving and long‑haul reliability. 🚗

Why this part is needed

The ECU must know how much air enters the engine to mix the correct fuel. A healthy MAF prevents lean knocks, rich soot, and poor drivability. It’s a direct‑fit replacement designed to restore factory performance and pass emissions checks.

How it works

Inside is a heated film/wire. Incoming air cools it; the sensor adjusts current to keep temperature stable. That change becomes a signal the ECU uses to calculate air mass, injector pulse width, and timing. Result: precise combustion in all conditions. ✅

What happens if it’s broken

• Rough idle, stalling, or hesitation
• Hard starting and weak acceleration
• High fuel use, black smoke, sulfur smell
• Check Engine Light (often P0101–P0104)
• Limp mode and possible catalyst damage if ignored

Install & tips 🔧

Mount in the intake tube after the air filter. Follow the airflow arrow, seat the O‑ring, and torque evenly. Do not touch the sensing element. Fix vacuum leaks, use a fresh filter, clear codes, and perform idle/ECU relearn. ⚠️
