100% new, never remanufactured, so there's no leftover debris that can cause sensor failure. 100% computer-tested to ensure the ECU receives accurate airflow readings under hard engine conditions, which are required to balance and deliver the correct air/fuel ratio to the engine in order to achieve clean burns. Dual-heated sensing elements ensure superior performance in any air/fuel system. High-quality sensing elements in airflow meter withstand changes in supply voltage. Manufactured to strict quality standards to ensure each part outperforms other air flow sensors in aftermarket.
