Masuma Mass Air Flow (MAF) sensors are a critical part of the engine’s electronic management system. By accurately measuring the volume of air entering the engine, they allow the ECU to calculate the exact amount of fuel required for an optimal air-fuel mixture. This ensures efficient engine performance, reduces fuel consumption, and helps lower emissions.
Masuma MAF sensors deliver a reliable combination of durability, precision, and OEM-level engineering. Key features include:
- Wire-type sensing element
Faster and more accurate measurements compared to traditional film-type sensors. - Platinum hot wire
More resistant to corrosion and high temperatures than standard tungsten elements, extending service life. - Bypass airflow channel
Minimizes contamination of the sensing element and improves sensor stability. - Glass-coated hot wire
A protective glass layer shields the sensor from dust and deposits, ensuring consistent accuracy even in harsh conditions.
