Iridium IX Spark Plug Product Line Details

The Iridium IX Spark Plug line by NGK is designed to provide enhanced ignition performance through the use of a fine iridium center electrode tip. This design improves spark efficiency and electrode longevity compared to conventional plugs. The 97382 part number belongs to this line, offering a combination of copper core conductivity and iridium tip durability, suitable for secondary ignition systems in a wide range of vehicles.

Technical Description and Attributes

This NGK spark plug features a copper core center electrode that ensures excellent electrical conductivity, paired with an iridium tip that resists wear and maintains a consistent spark over time. The taper cut ground electrode tip design increases spark exposure, contributing to more efficient combustion. The ground electrode is made from nickel, providing durability under high temperatures. The plug has a flat seat type and a thread diameter of 14mm with a reach of 0.75 inches, making it compatible with many classic and modern vehicles. The pre-gap is set at 0.040 inches, optimized for ignition performance, and the heat range of 4 balances heat dissipation and fouling resistance.

Compatible Vehicles and Applications

• Compatible with Bentley, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Jeep, Mercury, Oldsmobile, Plymouth, Pontiac, and Rolls-Royce vehicles
• Suitable for models such as Camaro, Charger, Cherokee, Eldorado, Firebird, Grand Caravan, Impala, LeBaron, Malibu, Monaco, Ramcharger, Skylark, Town & Country, and Wagoneer
• Designed for secondary ignition systems requiring a 14mm thread diameter and 0.75 inch reach

Common Issues Addressed by NGK 97382 Spark Plug

• Misfiring or rough engine idle due to worn or inefficient spark plugs
• Reduced fuel efficiency caused by incomplete combustion
• Difficulty starting the engine in cold or damp conditions
• Engine hesitation or loss of power under acceleration
• Excessive emissions from incomplete fuel burn

Installation Notes and Tips

Ensure the spark plug gap is set to the specified 0.040 inches before installation if adjustment is necessary. Use a 13/16 inch socket wrench for proper tightening to avoid damage to the flat seat. Confirm compatibility with your vehicle’s make and model, especially for classic and performance cars listed in the fitment. Avoid over-tightening to prevent thread damage. The non-removable nut electrical terminal type requires a secure connection to the ignition wire.
