U-Groove Spark Plug Design

The Denso 6047 is a conventional spark plug built around a U-Groove ground electrode design for improved ignitability. It uses a copper core center electrode with nickel tip materials to support consistent spark delivery and efficient combustion.

  • U-Groove ground electrode design for stronger ignitability
  • Copper core center electrode for stable heat transfer
  • Nickel tip materials for durable spark performance
  • Flat seat, 14.00 mm thread diameter, and 12.70 mm reach
  • Pre-gapped to 1.0 for straightforward service replacement

Detailed Product Overview

As part of Denso’s U-Groove Conventional line, this spark plug focuses on reliable secondary ignition performance with a design that helps the flame kernel form more efficiently. The nickel ground electrode and nickel-tipped center electrode work with the copper core to balance conductivity and durability, while the 20.6 mm hex size and flat seat support standard service fitment. The Denso 6047 is a practical replacement choice for applications that call for this specific plug configuration, including Yamaha YR2 fitment. This part cross-references Denso Auto Parts (e.g., W24FS-U10) for the same application.

What It Is Used For

  • Restoring weak or inconsistent spark output
  • Addressing rough idle caused by worn plug electrodes
  • Replacing fouled plugs that affect combustion efficiency
  • Correcting misfire symptoms tied to ignition wear

Installation Notes and Tips

Verify thread diameter, reach, seat type, and pre-gap before installation. Confirm the application matches the specified Yamaha YR2 fitment and use the listed plug configuration for proper service replacement. The Denso 6047 should be installed to the manufacturer’s specified torque for the engine.

Quality Assurance

Denso’s U-Groove Conventional spark plug line is engineered for dependable ignition performance and efficient combustion in service applications.
