DENSO 5026 Standard Spark Plug U-Groove Design

The DENSO 5026 is a standard spark plug engineered to deliver reliable ignition performance for a wide range of engines. This spark plug features DENSO's innovative U-Groove ground electrode design that creates a larger, more robust spark kernel compared to conventional spark plugs.

Key Features:

• U-Groove ground electrode design for improved ignitability and combustion efficiency
• Standard copper core construction for excellent heat dissipation
• Nickel-plated housing resists corrosion and seizure
• Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
• Purified alumina powder insulator for superior dielectric strength and thermal conductivity

The U-Groove design directs the spark to the optimal location in the combustion chamber, promoting more complete fuel burn and increased engine efficiency. This results in improved throttle response, better fuel economy, and reduced emissions. DENSO spark plugs meet or exceed OEM specifications and are backed by decades of engineering expertise as a leading original equipment supplier.
