Breathe easy with WAI's state of the art Mass airflow sensors  Our patented onboard interference filtering technology provides accurate readings of air flow, humidity, air velocity and air temperature to the vehicle ECU. We use a 4 layered mirco chip with a B2 micro controller to constantly deliver accurate data to to the ECU at micro second speeds to support the ECU in rapidly reacting to driving conditions and ensuring power and efficiency targets are met.
