• Description:

  This genuine Subaru spark plug plays a vital role in a vehicle’s engine by producing the electrical spark needed to ignite the fuel and air mixture stored in the engine’s combustion chambers. While this auto part does not sustain the electrical spark, it helps transfer the heat away from the combustion chambers into the water jacket of the cylinder head to start a vehicle’s engine. Finding the right spark plug replacement is important since this component gets worn out after lengthy use despite its sturdy construction. Every time a spark plug ignites, bits of metal chip off, which increases the necessary voltage to power a vehicle and keep it in that state for a long time. Buy this original equipment manufacturer (OEM) spark plug for Outback, Legacy, Impreza, Forester, Crosstrek, and XV Crosstrek models from SubaruOnlineParts. This durable and easy to install spark plug is a 100% original Subaru product and not an aftermarket part.
