Detailed Product Description

The NGK Racing Spark Plug 3230 is part of NGK's Racing Spark Plug line, designed specifically for high-performance and racing applications. This spark plug features a copper core center electrode that improves thermal conductivity and electrical efficiency, paired with a nickel ground electrode for durability under demanding conditions. The standard ground electrode tip and configuration ensure consistent spark generation, while the 5000 ohm resistance helps reduce electrical noise and interference. The removable nut electrical terminal type allows for easy installation and secure connection. With a pre-gap size of 0.024 inches and a heat range of 9, this spark plug is suited for engines requiring a cooler plug to prevent pre-ignition and maintain optimal combustion.

Common Applications and Issues Addressed

• Improves ignition reliability in high-performance vehicles
• Reduces misfires caused by electrode wear or improper gap
• Helps maintain consistent engine power output
• Prevents fouling in engines with aggressive tuning
• Supports stable combustion in racing and modified engines

Installation Notes and Tips

Ensure the spark plug gap is set to the recommended 0.024 inches before installation. Use a 13/16 inch socket for proper tightening to avoid damage to the flat seat. The 14 mm thread diameter and 0.75 inch reach are compatible with many performance engines, but always verify fitment with your specific make and model. The removable nut terminal allows for flexible ignition wire attachment. Avoid over-tightening to prevent thread damage.
