Bosch Alternator P/N:AL559N
Bosch AL4318X alternator for the 2011 Subaru Impreza H4 2.5L charges the battery and powers the electrical system. It is a remanufactured Bosch alternator designed to be identical in fit and performance to original equipment parts.
A battery warning light, dim headlights or a battery that keeps going flat can mean the alternator is worn, though a loose or worn drive belt or a weak battery can be behind them too, so find the cause before replacing the alternator.
This Subaru Impreza alternator is a direct-fit replacement for the 2011 model with the H4 2.5L engine.
