About the U-Groove Conventional Product Line

The U-Groove Conventional spark plug line by Denso features a unique U-groove ground electrode tip design that enhances spark exposure to the air-fuel mixture. This design supports better ignition efficiency and combustion stability compared to traditional flat electrode plugs. The conventional construction with nickel and copper materials balances durability and conductivity, making it suitable for many gasoline engines requiring reliable secondary ignition components.

Technical Details and Specifications

The Denso 4096 spark plug is engineered with a nickel ground electrode core and tip, providing resistance to wear and corrosion. The copper center electrode core enhances thermal conductivity, while the nickel tip ensures consistent spark delivery. With a pre-gap size of 0.9 mm and a single ground electrode, this spark plug maintains a stable spark gap for efficient ignition. The flat seat type and 19.00 mm reach ensure proper fitment in compatible engines, while the 12.00 mm thread diameter and 18.0 mm hex size facilitate straightforward installation. The manufacturer heat range of 24 is designed to suit a variety of engine operating temperatures, and the 5000 ohm resistance helps minimize electromagnetic interference with vehicle electronics.

Compatible Applications and Common Issues Addressed

  • Replacement for worn or fouled spark plugs causing misfires
  • Improves ignition stability in engines experiencing rough idling
  • Helps restore fuel efficiency by ensuring proper combustion
  • Reduces engine hesitation during acceleration
  • Addresses spark plug electrode wear affecting ignition timing

Installation Notes and Tips

When installing the Denso 4096 spark plug, ensure the spark plug gap is set to the specified 0.9 mm pre-gap size if adjustment is needed. Use a torque wrench to tighten the plug to the vehicle manufacturer’s recommended specifications to avoid damage to the threads or improper sealing. The 18.0 mm hex size allows for compatibility with standard spark plug sockets. Verify compatibility with your vehicle’s make and model before installation to ensure proper fitment.
