The Walker Products Air Charge Temperature Sensor (part number 210-91051) is a direct-fit replacement for 1997-2006 Audi and Volkswagen vehicles with 2.8L, 1.8L, and 2.7L engines. Air Charge Temperature Sensors measure air temperature through changing resistance and send this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered.
Features:
- Improved Fuel Efficiency: By accurately monitoring the incoming air temperature these sensors help the engine's electronic control unit (ECU) adjust the air-fuel mixture for improved fuel efficiency reducing fuel consumption and emissions.
- Enhanced Engine Performance: These sensors contribute to better engine performance by ensuring the engine receives the right amount of air, which is crucial for combustion efficiency, reduced engine knock, and increased horsepower.
- Precision Temperature Measurement: High-quality Air Charge Temperature Sensors provide accurate temperature readings, ensuring your vehicle's engine operates at the optimal temperature for maximum efficiency and performance.
- Longevity and Reliability: High-quality sensors are built to withstand harsh environmental conditions, ensuring long-lasting performance and reducing the risk of sensor failure, which can lead to engine issues.
- Emissions Reduction: With precise temperature data, Air Charge Temperature Sensors aid in reducing harmful emissions by enabling the ECU to optimize combustion, resulting in a cleaner and more environmentally friendly engine operation.
