TAKUMI spark plugs are manufactured with a complete quality management system - from incoming material inspection to outgoing 100% spark and seal testing.
Product Overview
TAKUMI S-R6A12 spark plug is a form, fit and function equivalent replacement for OEM part 12453572. TAKUMI S-R6A12 is a drop-in prechamber spark plug for MWM TCG 2020 and CAT CG 170 gas engines. 8-hole prechamber design, M18x1.5 thread, 0.3 mm gap. Installs without engine parameter changes.
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.
Replaces 1245-2074 (updated from old version 1230-1641) for MWM TCG 2020.

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.
