NGK B10EG Racing Spark Plug

NGK B10EG Racing Spark Plug

The NGK B10EG is a purpose-built racing spark plug designed to handle the extreme demands of high-revving two-stroke kart engines. Featuring a fine wire nickel alloy center electrode, this non-resistor plug delivers dependable high-RPM ignition and consistent combustion lap after lap.

The heat range number in the plug designation is an important tuning tool — use a hotter plug in cooler conditions and a cooler plug in warmer conditions. Moving from a cooler to a hotter plug effectively leans the motor out slightly, making heat range selection a key part of your race day setup.
