Standard Motor Products 221036M Mass Air Flow Sensor MAF Sensor

The Standard Motor Products 221036M is a direct-fit replacement Mass Air Flow (MAF) Sensor designed for Volkswagen and Audi vehicles. The MAF sensor monitors the volume and density of air entering the engine, allowing the Engine Control Unit (ECU) to precisely calculate the correct fuel injection quantity for optimal combustion across all operating conditions.

A failing or contaminated MAF sensor can cause a range of drivability problems including rough idle, poor acceleration, increased fuel consumption, and excessive exhaust emissions. Replacing it with a quality aftermarket sensor restores proper air-fuel metering and returns engine performance to factory specification.

Key Features:

• Direct-fit replacement — no modifications required
• Restores proper air-fuel ratio and fuel efficiency
• Helps resolve rough idle, hesitation, and poor acceleration symptoms
• Reduces exhaust emissions and clears related diagnostic trouble codes
• Built to meet or exceed OEM specifications for accuracy and durability
