Kia High Output Alternators

Kia's lineup runs from the Optima and Sportage that many people buy as a first new car to the Sedona minivan and the K900 luxury sedan. Owners add subwoofers, rear-seat screens and camping gear, and the charging system has to keep pace. Each Kia high output alternator here fits a 2011-2021 model, and the vehicle finder confirms which one matches your engine.

Four-cylinder and V6 Kias

The 2.0L and 2.4L four-cylinder models can choose between 240 and 320 Amp: the Kia Optima from 2011 to 2020 and the Sportage from 2011 to 2021. V6 owners have a 240 Amp unit. The Sorento is listed for the 2011 3.5L and 2015-2018 3.3L, the Sedona for 3.5L and 3.3L years between 2011 and 2018, the Cadenza for 2014-2016, and the K900 for 2015-2017 with the 3.8L.

The way owners use these vehicles varies widely. Optima owners commonly add a sealed subwoofer box and a mono amplifier. Sedona families run screens, tablets and a cooler on long drives, and Sorento owners add a hitch, trailer lighting and roof cargo lights. Cadenza and K900 owners usually want more power behind a premium audio upgrade without the lights flickering at night.

240 or 320 Amp for your Kia

A 240 Amp Kia high output alternator suits a single amplifier and subwoofer, or a Sedona powering screens and chargers for a full van. The 320 Amp unit, listed for the Optima and Sportage, gives more margin for multi-amp systems and extra lighting. Choose your year and engine in the vehicle finder first, because the Sorento and Sedona changed engines partway through these years.

Kia and Hyundai belong to the same company and use the same engine families, so these Mechman high output alternators also appear on our Hyundai alternator page for models such as the Sonata and Santa Fe. Round out the upgrade with a power and ground wiring kit, a battery from our batteries and the right part from harnesses and regulators. More makes are on our alternator collection.
