DENSO Auto Parts Spark Plug P/N:3370
DENSO Auto Parts 3085 spark plug for the 1993-2000 Yamaha XV535 Virago and other vehicles fires the spark that ignites the air-fuel mixture in the cylinder. The DENSO Auto Parts spark plug is OE-grade.
Hard starting, a misfire or rough running can mean a worn spark plug. Ignition and fuel parts can produce those signs too, so rule them out first. With the engine off and cool, a pulled plug can be checked for worn electrodes, a cracked insulator or oil fouling.
This single spark plug fits the 1993-2000 Yamaha XV535 Virago, the 1978-1995 Suzuki DS80 and the 1988-1990 Yamaha XV750 Virago; the XV535 Virago takes two plugs and the DS80 takes one. If your vehicle is not named here, look up its model and years in the Vehicles it fits section.
