Deliver a clean, consistent spark to every cylinder with the Pro Series Wire Spark Plug Wire Set 27590. This ignition wire set carries high-voltage current from the ignition system to the spark plugs, and it drops in as a direct-fit replacement for the 2005-2006 Saab 9-2X, 2005-2010 Subaru Forester, 2005-2011 Subaru Impreza, 2005-2009 Subaru Legacy, and 2005-2010 Subaru Outback.
Over time, spark plug wires can break down and leak voltage. If worn ignition wires are the cause, signs such as engine misfire, rough idle, hard starting, or radio static may indicate it's time to replace the set. Diagnose the cause before replacing, since these symptoms can also come from other ignition components.
