Core: converts low voltage from the battery to high voltage to provide ignition energy to spark plugs, ensuring proper engine combustion. Fits Subaru Outback 2.5L and Sport models, especially 6-cylinder version. After installation, can resolve acceleration stalls, idle roughness, and starting difficulties; fuel economy improves. If rapid acceleration causes hesitation, engine warning light on, or cold start requires multiple attempts, ignition coil aging is likely; replace early to protect catalytic converter.
