Autolite Spark Plug P/N:AI5703
Autolite XP6203 spark plug for the 2011-2014 Hyundai Sonata 4-cylinder 2.4L and other vehicles ignites the air-fuel mixture in the cylinder. This Autolite spark plug has an iridium-enhanced center electrode for a more focused ignition.
Hard starting, misfires or a rough idle can mean the plugs are worn, but a weak ignition coil or a fuel injector problem can be behind them too, so find the cause before replacing plugs.
It is also a spark plug for the 2010-2019 Kia Soul 4-cylinder 1.6L, the 2012-2016 Soul 4-cylinder 2.0L and the 2011-2015 Kia Optima 4-cylinder 2.4L. The plug count follows the engine; the 2011-2014 Hyundai Sonata 4-cylinder 2.4L takes four. If your car is not named here, look up its year, model and engine in the "Vehicles it fits" section.
