Make TOPRAN

The Mass Air Flow (MAF) sensor is a critical component in modern engine management systems. It accurately measures the volume and density of air entering the engine, providing vital data to the Engine Control Unit (ECU). This data allows the ECU to precisely calculate the amount of fuel needed for optimal combustion. A properly functioning MAF sensor contributes to improved fuel economy, reduced emissions, and consistent engine performance across various driving conditions. Replacing a faulty MAF sensor with this TOPRAN unit can restore lost power, eliminate rough idling, and resolve issues like poor acceleration and check engine lights. It is designed to meet or exceed original equipment specifications for a reliable fit and function.
