NGK Iridium Spark Plug for Yamaha R3
NGK Iridium Spark Plug for Yamaha R3
This is the same physical plug as our standalone NGK CR8EIX listing, just listed here by bike name for R3 owners who'd rather search by model than remember an NGK part code.
Since the R3 shares its spark plug spec with several other Yamaha and Honda sport bikes, it's worth checking your air filter condition at the same service interval. We stock both BMC air filter options for the R3.
