Subaru Forester Impreza / Legacy Mass Air Flow Sensor – OEM 22680-AA280

Overview

A new mass air flow sensor for Subaru Forester, Impreza and Legacy models, referenced to OE number 22680-AA280. The MAF sensor measures how much air the engine is drawing in and is the primary input for fuel delivery; when it drifts or fails you get a check engine light, hesitation on acceleration, erratic idle, poor fuel economy and sometimes a stall at traffic lights. It is one of the first components a workshop tests when a Subaru runs poorly, which makes it a dependable repeat-sale line. The manufacturer states the sensor is OE standard size, 12 volt, and carries a 12-month warranty.

Installation & Fitment Notes

Handle the sensor element carefully — it is delicate and easily damaged. Check the air filter and intake for leaks at the same time, and clear the fault codes before re-testing. We recommend professional installation by a qualified automotive technician. Confirm the OE number, engine code and vehicle details against your vehicle before ordering, and check that the part matches the unit being replaced.
