• Cross-reference: LZTR6AIX-11

Product Details

NGK’s Iridium IX line is aimed at performance-focused ignition service, combining an iridium center electrode with a nickel ground electrode tip and copper core center electrode construction. The fine-wire center electrode helps concentrate the spark, while the tapered cut ground design supports reliable ignition under demanding operating conditions. Part number 96762 is also identified as service number LZTR6AIX-11.

This spark plug is a direct service choice for select applications including 2020-2024 Dodge Durango, 2021-2024 Jeep Wrangler, 2023 Chrysler 300, 2023 Dodge Challenger, 2023 Dodge Charger, and 2022-2023 Jeep Grand Wagoneer. It is a fitment-focused option for owners searching for a 2020-2024 Dodge Durango spark plug, a 2021-2024 Jeep Wrangler spark plug, or NGK 96762 for late-model Chrysler and Dodge V8 applications.

What It Helps Address

• Hard starting caused by worn or inconsistent spark plugs
• Rough idle from degraded ignition performance
• Throttle hesitation during acceleration
• Misfire symptoms related to plug wear or fouling
• Reduced combustion efficiency in service intervals

Installation Notes

Verify the engine’s required plug specification before installation, including thread size, reach, seat type, and heat range. The pre-gap is listed at .044 in. / 1.1 mm, so confirm the engine’s required gap before use. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification to protect the threads and sealing surface.

Quality Assurance

NGK Iridium IX plugs are engineered for durability and consistent ignition performance in modern gasoline engines. The iridium center electrode uses a high-melting-point alloy suited to demanding combustion environments, and the tapered cut ground design supports dependable service in compatible applications such as the Dodge Durango, Jeep Wrangler, Chrysler 300, Dodge Challenger, Dodge Charger, and Jeep Grand Wagoneer.
