Description
Genuine Alternator for the 2015–2017 Subaru Outback
This is a brand-new, genuine Subaru alternator with OEM part number 23700AA91B. It is the same part installed at the factory on the Subaru Outback, so it matches the original fit, finish and performance — no trimming, adapters or guesswork. Mason’s Auto Store sells it below the manufacturer’s suggested retail price, ships it across the USA and checks every order against your vehicle before it leaves our Akron, Ohio counter.
Fitment notes from the factory catalog: Fits Legacy, Outback.
