This product is intended for automotive use only; do not use in aircraft.

• U-Groove ground electrode design for enhanced flame growth
• Machine rolled threads to prevent seizing or cross threading
• 100% pre-fired for assured high quality
• Purified alumina powder insulator for strength and thermal conductivity
• Five rib insulator to prevent flashover
• Copper-glass seal for a gas-tight bond between electrode and insulator

The Denso W16S-U Spark Plug stands out due to its unique U-Groove ground electrode design. This feature allows the flame a groove to grow in, reducing flame dissipation and creating a larger flame front. This results in a more complete combustion process, which translates to better fuel efficiency and a noticeable improvement in throttle response.

The machine rolled threads of the Denso W16S-U ensure smooth installation and removal, preventing issues like seizing or cross threading. Each spark plug is 100% pre-fired to guarantee the highest quality, ensuring reliable performance and longevity.

Constructed with a purified alumina powder insulator, this spark plug offers exceptional strength and thermal conductivity. The five rib insulator design prevents flashover, enhancing the overall durability and performance of the plug.

The copper-glass seal effectively bonds the center electrode and insulator, providing a gas-tight seal that enhances the spark plug's efficiency and reliability.

Choose the Denso W16S-U Spark Plug for an optimal blend of performance, efficiency, and durability. Designed for automotive use only, this spark plug will not only improve your vehicle’s engine performance but also contribute to fuel savings and a smoother driving experience.
