Factory & Quality Control
The testing equipment is calibrated regularly and all inspection records are kept for at least three years, supporting fast after-sales analysis.
Application
In continuous-duty generator applications, consistent ignition reduces misfire-related downtime and lowers maintenance cost over the engine's lifetime.
Production Workshop
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.
