DENSO Auto Parts Spark Plug P/N:5369
DENSO Auto Parts 3377 spark plug for the 2003-2007 Honda Accord 4-cylinder 2.4L or V6 3.0L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. It is made to OE performance, durability and emissions standards.
Hard starting, a rough idle or a misfire can mean the plugs are worn. These signs alone do not prove the plug is at fault; a weak ignition coil can produce them too. The 2003-2007 Honda Accord takes four plugs with the 4-cylinder 2.4L and six with the V6 3.0L.
This iridium spark plug is a direct-fit replacement for the 2003-2007 Honda Accord 4-cylinder 2.4L or V6 3.0L, the 2002-2005 Honda Civic 4-cylinder 2.0L and the 2011-2012 Ram 1500 V6 3.7L. If your vehicle is not named here, find your year, make and engine in the "Vehicles it fits" section.
