ENA Mass Air Flow (MAF) Sensor for Subaru 2008–2017 — Direct-Fit Replacement, 12‑Month Warranty

ENA Mass Air Flow (MAF) Sensor accurately measures incoming air for Subaru engines from 2008–2017, replacing part numbers 22680AA380 and 22680AA38A to restore proper air–fuel calculations.

This ENA MAF sensor is a direct-fit aftermarket replacement engineered for a broad range of Subaru models and engine sizes. It reads the amount of air entering the intake so the engine control module can adjust fuel delivery. Built to the shape and connector pattern of original equipment, it installs with basic hand tools and comes with a 12-month warranty.

Will this MAF sensor fit my Subaru model and year?

Compatibility covers many Subaru models and multiple engine configurations across the 2008–2018 model years. Use your vehicle details to confirm fitment against the listed reference numbers. Fitment includes both 2.0L and 2.5L H4 engines and select 3.6L H6 applications where specified.

• Compatible models: Forester, Outback, Impreza, Legacy, WRX, WRX STI, XV/Crosstrek.
• Covered years: commonly 2008 through 2017 (some listings extend to 2018).
• Reference part numbers: 22680AA380, 22680AA38A and OE cross-references provided.

How does the ENA MAF sensor affect engine performance?

The sensor provides real-time airflow data so the engine control module can calculate proper fuel injection and ignition timing. Replacing a faulty sensor helps recover smoother idling, steadier throttle response, and more consistent fuel trims. It does not tune performance, but it restores factory measurement accuracy.

• Restores correct air measurement for fuel metering and emissions control.
• Helps eliminate rough idle, hesitations, and poor fuel economy caused by bad MAF readings.
• Designed to match original connector and airflow path for reliable readings.

What should I expect during installation and maintenance?

Installation is straightforward: unplug the factory harness, unbolt the old sensor, swap in the ENA unit, and reconnect. No special calibration is typically required; however, clearing stored engine codes after replacement may be recommended. Periodic inspection and gentle cleaning of the intake and sensor housing can prolong service life.

• Tools needed: basic socket set and screwdriver; typical install time 15–30 minutes.
• Package includes one 5-pin air mass flow sensor and a 12-month warranty.
• Tip: avoid abrasive cleaning methods—use MAF-safe cleaner if needed.

What are the key technical and warranty details?

The ENA MAF sensor is manufactured to match OEM physical dimensions and electrical interfaces, with multiple OE cross‑reference numbers listed for fit verification. It comes backed by a 12-month warranty for peace of mind. Always verify exact fit using the vehicle lookup or the confirmed-fit tool before purchase.

• OE references: 22680-AA380, 22680-AA38A, and additional cross-references provided.
• Electrical: 5-pin connector compatible with specified Subaru harnesses.
• Warranty: 12 months from purchase; replace defective units to ensure accurate air mass measurement.

Who this is for: Drivers and DIY technicians who own compatible Subaru models and need a cost-effective, direct-fit replacement MAF sensor to restore accurate airflow readings. This ENA unit is suitable for people replacing a failed sensor, repairing drivability issues tied to air metering, or maintaining a used Subaru where the original part shows signs of age or contamination.
