NGK Iridium Motorcycle Spark Plug IFR8H11

The NGK Iridium Motorcycle Spark Plug IFR8H11 quickly dissipates large amounts of heat, preventing overheating and fouling and performs equally well in a hot or cold engine. Copper wire is used in place of the usual iron core, which dissipates heat quicker. It cools the electrode tip and insulator tip, which prevents hot spots that could cause pre-ignition.
