Product Details

The DENSO 6040 is a standard spark plug featuring U-Groove technology designed to deliver reliable ignition performance and improved engine efficiency. This spark plug is engineered to provide superior ignitability compared to conventional spark plug designs.

Key Features:

  • U-Groove ground electrode design for enhanced ignitability and more complete combustion
  • Standard resistor construction to prevent electromagnetic interference with vehicle electronics
  • Copper core center electrode for excellent heat dissipation and thermal conductivity
  • Durable nickel-plated shell for corrosion resistance and easy installation
  • Trivalent metal plating provides superior anti-corrosion and anti-seizing properties

DENSO spark plugs are manufactured to OEM specifications and provide reliable performance for a wide range of automotive applications. The U-Groove design creates a larger flame kernel at ignition, resulting in improved fuel efficiency and reduced emissions.
