Technical Details and Performance

The Denso 5323 spark plug features a copper core center electrode that enhances electrical conductivity, paired with an iridium tip that resists wear and maintains a consistent spark over time. The ground electrode uses a tapercut, u-groove design to increase spark exposure, which can contribute to better combustion efficiency. With a standard ground configuration and nickel core material, the spark plug maintains durability under typical operating conditions. The flat seat and 19.00 mm reach ensure compatibility with engines requiring these specifications, while the 0.8 mm pre-gap size supports optimal ignition timing.

Compatible Vehicles and Common Applications

• Replacement spark plug for vehicles requiring a 14.00 mm thread diameter and 19.00 mm reach
• Suitable for engines needing a heat range of 31
• Ideal for models that specify a flat seat spark plug with a 16.0 mm hex size
• Used in secondary ignition systems to maintain engine performance and fuel efficiency
• Addresses issues such as misfires, rough idling, and poor throttle response

Installation Notes and Tips

When installing the Denso Iridium Power 5323 spark plug, ensure the pre-gap of 0.8 mm is maintained or adjusted according to the vehicle manufacturer’s specifications. Use a 16.0 mm socket for proper torque application. Verify the flat seat type matches the engine’s cylinder head design to prevent sealing issues. Proper installation helps avoid cross-threading and ensures optimal spark plug performance.
