Yongtoparts Mass Air Flow Sensor MAF 22680AA380 for Subaru Forester/Impreza - Plug‑and‑Play, Thermal Film

Yongtoparts Mass Air Flow Sensor (MAF) 22680AA380 accurately measures incoming air for compatible Subaru engines, restoring correct air–fuel readings to the ECU.

If your Subaru is experiencing rough idle, reduced acceleration or increased fuel consumption, a failing mass air flow sensor can be the culprit. This Yongtoparts replacement MAF is designed to match OE fit and function for many 2008–2018 Subaru H4 and H6 engines. It uses a thermal film sensing element to provide stable, repeatable airflow data so the engine control unit can set proper fuel delivery and ignition timing.

How will this MAF sensor affect drivability?

A precise MAF gives the ECU reliable airflow information, which improves throttle response and steadies idle. Replacing a worn or contaminated sensor typically reduces hesitation during acceleration and can eliminate stumbling that occurs when the engine transitions between throttle positions.

• Restores accurate air measurement for smoother acceleration.
• Helps stabilize idle RPM and reduce surging.
• Prevents rich/lean conditions caused by incorrect airflow data.

Which Subaru models and engine sizes does this part fit?

This Yongtoparts unit is built to replace specific OE numbers and fit a broad range of Subaru models with 2.0L, 2.5L H4 and 3.6L H6 engines. Confirm compatibility by matching the OE part number or your vehicle year, engine code and intake connector layout.

• Compatible with Forester (2009–2018), Impreza (2008–2016), Legacy and Outback (2008–2018).
• Fits WRX and WRX STI (2012–2018 variants listed) and XV Crosstrek (2013–2015).
• Directly replaces OE numbers like 22680AA380, 197400-5111, MAS0317 and related codes.

Is installation difficult and what should I expect?

Installation is plug-and-play for most owners with basic tools: unclip the electrical connector, loosen the intake clamps, remove the old sensor and install the new unit. No programming is typically required; however, inspect connectors and intake tubing for leaks or contamination before reassembly.

• Simple plug-and-play replacement—no special tools usually needed.
• Inspect intake hoses and wiring for damage prior to install.
• If check-engine codes remain, perform a diagnostic scan and clear codes after replacement.

What performance and service assurances come with this part?

Yongtoparts MAF sensors use a sensitive thermal film element to deliver stable readings that help the ECU manage fuel and combustion more precisely. The product comes with a one-year after-sales warranty and responsive customer support to address fitment or functionality questions.

• Thermal film sensing element for precise airflow monitoring.
• One-year after-sale support and customer response within 24 hours.
• Engineered as an OE-style replacement for listed Subaru part numbers.

Who is this for: This replacement MAF sensor is aimed at Subaru owners, independent mechanics and DIY enthusiasts who need an OE-compatible airflow sensor for 2.0L/2.5L H4 and 3.6L H6 engines across Forester, Impreza, WRX, Legacy, Outback and XV Crosstrek years listed. Choose this Yongtoparts unit if your vehicle shows symptoms of incorrect air metering, or if diagnostics point to part numbers 22680AA380, 197400-5111, MAS0317 or equivalent. Always confirm fitment against your vehicle’s OEM part number and inspect the intake system during installation for reliable long-term operation.
