Standard Ignition MAS0510 Mass Air Flow Sensor

Mass Air Flow Sensor for Toyota and Lexus Applications

Standard Ignition MAS0510 is a new mass air flow sensor built as a sensor-only replacement with a bolt-on attachment method and a single rectangular plug-in connector. It uses a 5-blade male terminal layout and ABS plastic housing material for direct-fit service on select Lexus, Subaru, Scion, Suzuki, and Toyota vehicles.

Key Features

• Part number MAS0510 mass air flow sensor
• Sensor only; housing not included
• Bolt-on mounting with 2 bolt holes
• 1 rectangular female connector, plug-in type
• 5 male blade terminals
• New replacement part from Standard Ignition

Detailed Description

Standard Ignition MAS0510 is a replacement mass air flow sensor for vehicles that rely on accurate intake air measurement for engine management. It is listed for applications including Lexus IS300, IS350, NX300, RC350, and Toyota 86, along with Subaru BRZ and related models. This part cross-references Delphi AF10347 and Walker Products 245-1430 for the same application. If you are replacing a failing MAF sensor on a Lexus IS350, Toyota 86, or Subaru BRZ, MAS0510 provides the sensor-only format needed when the original housing remains in service.

What It Helps Address

• Rough idle caused by incorrect airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to air metering faults
• Poor fuel trim behavior from inaccurate sensor output
• Driveability issues after contamination or sensor wear

Installation Notes and Tips

Verify connector shape, terminal count, and bolt-hole layout before installation. This sensor uses a plug-in rectangular connector and bolt-on mounting, so the original housing must match the sensor-only design. Confirm vehicle coverage by year and model before ordering; fitment includes 2013-2020 Subaru BRZ, 2017-2020 Toyota 86, 2016-2020 Lexus IS300, and other listed applications such as Lexus NX300, RC350, ES300h, and Scion FR-S.

Quality Assurance

Standard Ignition supplies this as a new emission control sensor built for direct replacement service. The MAS0510 is cataloged against multiple OE and aftermarket references for the same application, including Lexus, Subaru, Scion, Suzuki, and Toyota fitments.
