Beck/Arnley Direct Ignition Coil P/N:178-8344
Beck/Arnley 178-8392 direct ignition coil for the 2004-2010 Subaru Forester H4 2.5L and other vehicles turns battery voltage into the high voltage a spark plug needs to fire. Each coil serves one cylinder, which is why these engines take four.
A weak coil can show up as a misfire, a rough idle or a flashing check engine light. Worn spark plugs or damaged wiring can also produce a misfire or rough idle, so with the engine off and cool, look the coil boot and connector over for cracks or burn marks before you buy.
This Beck/Arnley direct ignition coil fits the 2004-2010 Subaru Forester H4 2.5L, the 2005-2009 Subaru Outback H4 2.5L and the 2004-2010 Subaru Impreza H4 2.5L, and it matches OE form, fit and function. If your car is not one of these, look up your year and engine in the "Vehicles it fits" section.
