NGK Spark Plug P/N:LFR6A
NGK LFR6A-11 spark plug for the 2001-2004 Subaru Outback H6 3.0L fires the spark that ignites the air-fuel mixture in each cylinder. As one of the NGK spark plugs in the V-Power line, it is engineered for OE applications and improves ignitability over standard nickel plugs.
Hard starting, a rough idle or a misfire can be a sign of worn plugs. Before you replace them, rule out the ignition coils, fuel delivery and vacuum leaks, since those can bring on a similar complaint. This listing is one plug.
It is a Subaru Outback spark plug for the 2001-2004 model with the H6 3.0L engine, which takes six. It suits engines fitted with nickel alloy plugs from the factory and is not recommended where factory precious metal plugs are fitted.
