OE numbers are for reference only. Final fitment should be confirmed before ordering.

Factory & Quality Control

Each unit is 100% tested for spark performance and gas tightness. Random samples from every batch also undergo dimension and material verification.

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.
