DENSO Auto Parts Spark Plug P/N:5319
DENSO Auto Parts 3168 spark plug for the 2000-2009 Subaru Outback H4 2.5L and other vehicles ignites the air-fuel mixture in the cylinder with an electrical spark. This double platinum spark plug is made to OE performance, durability and emissions standards.
Hard starting, a rough idle, a misfire or poor fuel economy can mean a spark plug is worn. These signs alone do not prove the plug is at fault; a weak ignition coil is another common source of a misfire.
This double platinum spark plug fits the 2000-2009 Subaru Outback H4 2.5L, the 1998-2004 Subaru Forester H4 2.5L and the 2006-2009 Audi A4 4-cylinder 2.0L, along with many other vehicles. If your car is not named here, look up its years and engine in the "Vehicles it fits" section.
