Detailed Product Description

The Denso 3432 spark plug belongs to the Iridium Long Life product line, which focuses on durability and consistent ignition performance. The iridium center electrode tip provides a fine spark gap that improves ignition efficiency and extends the plug's lifespan. The copper core center electrode enhances thermal conductivity, helping to dissipate heat effectively. The ground electrode features a platinum chip tip and a thick nickel core, which contributes to wear resistance and stable spark generation. With a pre-gap size of 1.1 mm and a flat seat design, this spark plug ensures proper fitment and reliable sealing in the combustion chamber. The 14 mm thread diameter and 19 mm reach are compatible with Honda Civic models requiring this specification.

Compatible Vehicles and Applications

This spark plug is specifically compatible with Honda Civic models that require a 14 mm thread diameter and 19 mm reach spark plug. It is designed to maintain optimal ignition performance and fuel efficiency in these vehicles.

• Resolves misfires caused by worn or damaged spark plugs
• Improves cold start performance and throttle response
• Reduces engine knocking and pinging
• Helps maintain fuel economy by ensuring complete combustion
• Minimizes ignition system electrical interference with 5000 ohm resistance

Installation Notes and Tips

When installing the Denso 3432 spark plug, ensure the pre-gap is set to 1.1 mm if adjustment is necessary. Use a 16 mm socket wrench for proper torque application. The flat seat design requires careful seating to avoid leaks. It is recommended to replace spark plugs in sets to maintain consistent engine performance. Always follow the vehicle manufacturer’s torque specifications and installation procedures.
