C-Tzu Mass Air Flow Sensor MAF

C-Tzu Mass Air Flow (MAF) Sensor is an OEM-equivalent replacement that measures incoming air to restore proper engine fuel-air balance and drivability.

If your Toyota, Lexus, Mazda or Scion is showing hesitation, rough idle, or reduced fuel economy, a worn or failing MAF sensor can be the cause. This C-Tzu assembly is engineered to match original equipment fit and function, replacing common OE part numbers so you can swap it in without modification. It’s built to the dimensions and electrical specifications of factory units, helping return consistent airflow readings and smoother performance.

How will this MAF sensor affect my vehicle’s performance?

Accurate airflow measurement is essential for the engine control unit to calculate the correct fuel delivery. A properly functioning MAF sensor reduces stumbling, erratic idle, and drivability issues by giving the ECU reliable input.

• Restores stable idle and throttle response.
• Helps correct fuel trim for better economy.
• Reduces hesitation and surging during acceleration.

Which vehicles and part numbers does it replace?

This C-Tzu MAF assembly covers a broad set of vehicles across Toyota, Lexus, Mazda, and Scion lines. It directly replaces many common OE references so installation is straightforward on compatible models.

• Replaces OE numbers like 22204-21010, 197-6020, L321-13-215, and more.
• Fits popular models such as Camry, Prius, Tacoma, ES300, RX300, and select Mazda vehicles.
• Always verify your vehicle year, engine code, and connector style before purchase.

What can I expect from fit and reliability?

C-Tzu designs this MAF to match the factory sensor’s mounting points, electrical connector, and airflow path. Materials and finish are chosen to endure engine bay conditions, reducing the chance of premature failure when installed correctly.

• OEM-equivalent dimensions for simple bolt-on replacement.
• Durable housing and connector built for engine-bay exposure.
• Backed by a 1-year warranty against manufacturing defects.

How should I confirm compatibility before buying?

Compatibility depends on the vehicle’s year, engine variant, and the exact OE part number. Cross-reference your existing part number or consult your service manual to ensure a match.

• Check the OE number stamped on your old sensor against the replacement list.
• Compare electrical connector shape and mounting points visually.
• Contact seller with your VIN or engine details if unsure.

Who is this for: This C-Tzu MAF sensor is aimed at owners and technicians who need a reliable, direct-fit replacement for failing mass air flow sensors on Toyota, Lexus, Mazda, and Scion models. It’s suited for DIY mechanics wanting a straightforward swap and repair shops sourcing an affordable OEM-equivalent part that restores proper airflow sensing and engine drivability.
