DENSO Auto Parts Spark Plug P/N:3370
DENSO Auto Parts 3395 spark plug for the 2003-2005 Honda Civic 1.3L and other vehicles lights the air-fuel mixture in the cylinder with an iridium center electrode tip.
A misfire, hard starting or a rough idle can point to worn plugs, but ignition and fuel faults can show up the same way. With the engine off and cool, look at a removed plug's electrode tip and insulator for wear, deposits or cracks before you replace it. Plug count varies by engine: the 2003-2005 Honda Civic 1.3L takes eight, so buy the full set and fit them together.
The vehicles it fits include the 2005-2010 Subaru Forester 2.5L and the 1999-2010 Hyundai Sonata 2.5L, 2.7L and 3.3L. Driving something else? Look up your car in the "Vehicles it fits" section.
