High‑Precision Mass Air Flow Sensor (MAF) ⚙️

Keep your engine breathing right with a calibrated airflow meter that restores factory performance. This sensor reads the exact volume and temperature of incoming air so the ECU can calculate the perfect fuel mix. Expect quicker starts, stable idle, sharper throttle response, lower emissions, and better mpg ⛽.

Why you need it

Modern engines rely on accurate airflow data to protect the catalytic converter and maintain smooth power. Age, contamination from dusty filters, or intake changes can skew readings. Replacing a tired MAF brings back consistent fueling and reliable drivability ?.

How it works

Inside is a hot‑film element kept at a fixed temperature. As air passes, it cools the film; the circuit increases current to hold temp and converts that demand into a grams‑per‑second signal. A shaped housing and flow straightener reduce turbulence for precise ECU control.

What happens if it’s bad

Symptoms include rough idle, hesitation, hard starts, poor economy, black smoke, and a lit check engine lamp. The ECU may run rich/lean, trigger limp mode, foul plugs, and overheat the cat ❗ Clean, dry filter only; install with the arrow toward the engine and clear codes after replacement ?.
