NGK DPR8EA-9 spark plug for the 1993-2009 Honda XR650L 644cc and other vehicles ignites the fuel and air in the cylinder. It is one of the NGK spark plugs in the Standard line, made for vehicles with nickel alloy plugs rather than factory precious metal ones.
- NGK Standard line plug with a nickel alloy center electrode for consistent performance
- Trivalent metal plating for anti-corrosion and anti-seizing properties and easier installation and removal
- High grade alumina silicate ceramic insulator for dielectric performance
- Solid 98% pure copper core for heat dissipation, conductivity and ultra wide heat ranges
- Cold-rolled threads that prevent cross-threading and damage to cylinder heads
- Triple gasket sealing against combustion gas leakage

A worn plug can show up as hard starting, a misfire or a rough idle, though other ignition or fuel problems can look alike. Before replacing it, pull the plug with the engine off and cool and look at the tip for oil, deposits or a cracked insulator, which can point to a cause elsewhere. The 1993-2009 Honda XR650L 644cc takes one plug, and the count varies by vehicle.
