Product Overview

Widely ordered as the DEUTZ-numbered equivalent for the same ignition position, this plug is cross-referenced against the DEUTZ numbering used on MWM gas engine series.

DEUTZ and MWM part numbers for the same plug often appear together on engine documentation, which is why operators end up holding several numbers for one component. The cross-reference table on this page maps each number to the engine models it serves, so the correct part can be confirmed from whichever number you have.

This shielded plug is used on MWM TCG 2032 and C-A-T CG 260 units in biogas, natural gas and landfill gas power stations, where the long shielded cable reaches the ignition position without an extension piece.

Fuel flexibility: the same plug can serve natural gas, biogas and landfill gas installations, but the replacement interval should be shortened as fuel quality deteriorates.

Packing, Delivery & Customization

Production & Quality Control

Every TAKUMI plug comes off a vertically integrated line: precision grinding, laser welding, ceramic sintering and a full electrical test. Batch numbers are recorded for full traceability.

The stations below are the ones every production batch passes through — pressure and leakage, spark voltage analysis, ceramic high-voltage resistance, and an aging run. A plug only ships once it has cleared all four.

Pressure & leakage test

Spark voltage analysis

Ceramic high-voltage resistance test

Aging test

Quality is checked at the point of manufacture rather than at the point of complaint. That is what keeps behaviour consistent from the first plug of a set to the last.

Our production and quality system:

• Produced in ISO 9001 and IATF 16949 certified facilities.
• 100% tested before shipment — spark gap, resistance and seal checked unit by unit.
• Factory-direct supply chain, so specification consistency is maintained batch to batch.

FAQ

Q: How do I know it fits my engine?
A: Send us your engine model and serial number, or the OEM part number currently in the engine. We will cross-check it against our reference list and confirm before you order.

Q: How long will the plug last in service?
A: Our design life for the S-R6A13 is 2,000–3,000 hours at full load. Actual service life depends on gas quality, load profile and maintenance regime.

Q: Do you supply samples?
A: Samples are not supplied free of charge. Sample cost is negotiable — please contact us with your target model and delivery address.

Q: Can you supply under our own brand?
A: Yes — unbranded, your brand/logo, or custom packaging. Minimum quantities apply for custom branding.

Q: What is the minimum order quantity?
A: 20 pcs per item.

Q: What if a plug fails?
A: We warrant our spark plugs against manufacturing defects for a limited period from delivery. Spark plugs are consumable items: the warranty does not cover normal wear, damage from incorrect installation, engine faults, fuel or gas quality problems, or use outside the specified application.
