BSE Original 221359 Mass Air Flow Sensor Remanufactured, 4-Pin Female Connector

The BSE Original 221359 is a remanufactured mass air flow (MAF) sensor designed as a direct-fit replacement for a wide range of Toyota, Lexus, Subaru, Scion, Suzuki, Volvo, and Pontiac vehicles. The MAF sensor measures the volume and density of air entering the engine and relays that data to the engine control module, enabling precise fuel delivery, smooth idle, and optimal combustion efficiency. A failing or contaminated mass air flow sensor commonly triggers a check engine light, rough idle, poor fuel economy, or hesitation under acceleration — making accurate replacement critical to restoring proper engine performance.

Key Features:

• Remanufactured mass air flow sensor
• Bolt-on mounting for straightforward installation
• Single female connector with 4 male pin terminals
• Plastic housing construction
• No ECM flash or reprogramming required after installation
• Contents: sensor only (housing not included)
• Backed by a 1-year / unlimited-miles warranty

Engineered to OE specifications, this remanufactured MAF sensor offers a cost-effective alternative to a new unit without sacrificing fit or function. Fits select 2009–2025 Toyota, Lexus, Suzuki, Subaru, Scion, Volvo, and Pontiac models — confirm compatibility with your specific year, make, and model before ordering.
