Genuine Fuel Injector for the 2015–2019 Subaru Outback with the 2.5L boxer 4 (FB25)
This is a new, genuine Subaru fuel injector with OEM part number 16611AA88A, engineered for the 2.5L boxer 4 (FB25) engine in the 2015–2019 Subaru Outback. Leaking or clogged injectors cause misfires, fuel smell, rough idle and failed emissions tests. Genuine injectors match the factory flow rate and spray pattern for this engine. Mason’s Auto Store sells it 33% below the manufacturer’s suggested retail price and ships it across the USA from our Battle Creek, Michigan warehouse.
Catalog fitment notes: Except California.
