Quality starts at the factory floor. TAKUMI's production facility combines automated assembly with skilled craftsmen, and every batch is documented and traceable.
TAKUMI A7RTC spark plug. TAKUMI A7RTC iridium spark plug matching NGK CR7EIX.
Every TAKUMI unit is produced in an ISO 9001 and IATF 16949 certified factory, 100% tested before shipment. The plug is engineered for long service life in continuous operation, with a nickel-plated shell, copper-core electrode and high-grade ceramic insulator.
OE numbers are for reference only. Final fitment should be confirmed before ordering.

In our quality laboratory, every production batch is inspected with precision gauges, high-voltage spark testers and sealing equipment before packing.
TAKUMI runs a fully integrated manufacturing base: CNC machining, automated assembly and 100% functional testing under one roof.



From raw material to finished spark plug, every process is controlled in-house with ISO-certified procedures.
