About the U-Groove Conventional Brand Line

The U-Groove Conventional line from Denso focuses on spark plugs with a unique U-shaped groove in the ground electrode tip. This design enhances spark exposure and improves ignition efficiency while maintaining a conventional electrode structure. The Denso 3167 spark plug benefits from this design by delivering consistent ignition performance tailored for secondary ignition systems in vehicles like the Honda Civic.

Detailed Product Description

The Denso 3167 spark plug is engineered with a copper core center electrode to provide excellent thermal conductivity, ensuring efficient heat dissipation during operation. The nickel ground electrode and tip materials offer durability and resistance to wear, which is critical for maintaining spark quality over time. With a resistance rating of 5000 ohms, this spark plug helps reduce electromagnetic interference while supporting stable ignition. The 1.1 mm pre-gap size is factory set to optimize combustion efficiency and engine performance in Honda Civic models. Its 19 mm reach and 14 mm thread diameter ensure proper fitment and sealing with the engine cylinder head, while the flat seat type provides a secure and reliable installation.

Compatible Applications and Common Issues Addressed

• Compatible with Honda Civic models requiring a 14 heat range spark plug
• Helps resolve misfires caused by worn or damaged spark plugs
• Improves cold start performance and throttle response
• Reduces engine hesitation and rough idling
• Supports consistent ignition timing for smoother engine operation

Installation Notes and Tips

When installing the Denso 3167 spark plug, ensure the pre-gap is checked and adjusted if necessary to 1.1 mm for optimal performance. Use a 16 mm socket wrench for proper torque application to avoid over-tightening or damage to the spark plug or cylinder head. It is recommended to install spark plugs when the engine is cool to prevent thread damage. Always follow the vehicle manufacturer’s specifications for torque and installation procedures.
