NGK Spark Plug P/N:DR8HS
NGK BPR8ES spark plug for the 2010-2011 Cobra CX50-SR 50cc and other vehicles ignites the air-fuel mixture in the cylinder. It is one of the NGK spark plugs in the Standard line, engineered for OE applications.
A worn plug can show up as a misfire, a rough idle or hard starting. Ignition coils, plug wires and fuel delivery can also be behind those signs, so track down the cause before buying a plug. This plug is best for engines that run nickel alloy plugs, and it is not recommended where the factory plugs are precious metal.
The 2010-2011 Cobra CX50-SR 50cc, the 2011 Cobra CX50-JR 50cc and the 2004-2007 Aprilia Mojito Custom 50 49cc are among the vehicles this plug fits, along with many more. Each of them takes one plug, while the count per vehicle varies elsewhere in the range. Riding or driving something else? Look up your year and engine in the "Vehicles it fits" section.
