DENSO U-Groove Spark Plug

DENSO U-Groove spark plugs are conventional nickel spark plugs. They are built for reliable ignition and dependable engine performance in a wide range of applications. A U-shaped groove is machined into the ground electrode. DENSO designed this feature to improve flame propagation, which supports efficient combustion, smooth idle, and good throttle response.

Key Features:

• U-groove ground electrode: The groove exposes more of the spark to the air-fuel mixture, which promotes efficient flame growth and combustion.
• Nickel alloy electrodes: They give dependable ignition and durability in everyday service.
• OE-quality construction: DENSO is a leading original equipment supplier to automakers worldwide, and these plugs use the same manufacturing standards.
• Quality ceramic insulator: It provides strong electrical insulation and heat resistance.
• Consistent performance: They support easier starting, smooth running, and good fuel efficiency when used with the correct heat range and gap.

Choose the correct individual spark plug part number for your engine, and follow the manufacturer's recommended gap and torque specifications. Replacing worn spark plugs at the recommended interval helps maintain smooth engine operation and efficient combustion.
