NGK 96835 Air Mass Meter

NGK 96835 Air Mass Meter – Precision in Every Breath

The NGK 96835 Air Mass Meter is a high‑performance sensor designed to measure the exact amount of air entering an engine’s combustion chamber. By providing accurate airflow data, it enables the engine control unit (ECU) to calculate the optimal fuel injection quantity, ensuring efficient combustion, reduced emissions, and improved vehicle performance.

Key Functionalities

• Accurate Airflow Measurement: Utilizes a hot‑wire or hot‑film sensor element that heats up and cools down in response to the volume of air passing through. The resulting temperature differential is converted into an electrical signal proportional to mass airflow.
• Wide Operating Range: Capable of handling low idle speeds as well as high engine loads, maintaining precision across a broad spectrum of operating conditions.
• Fast Response Time: Rapidly adapts to changes in throttle position and engine load, providing real‑time data for the ECU to adjust fuel delivery instantly.
• Robust Construction: Built with high‑temperature resistant materials that withstand harsh engine bay environments, ensuring long service life even under extreme conditions.
