• Ruthenium center electrode tip for high ignitability
• Dual fine electrode ground tip design for stable spark performance
• Copper core center electrode for efficient heat transfer
• 10000 ohm resistor for ignition noise suppression
• Flat seat, 14 mm thread diameter, 5/8 hex size
• Pre-gapped at .040 inches from the factory; some listed vehicles require adjustment to .032 or .044 inches
• NGK part number 92375, also listed as FR5AHX-E

Product Details

As part of NGK’s Ruthenium HX High Ignitability line, this spark plug is engineered for vehicles that need reliable ignition response and consistent combustion quality. NGK’s long OE supply history and broad coverage across domestic and import applications make the 92375 a practical replacement for owners servicing ignition systems on Chrysler 200, Dodge Avenger, and related platforms.

This part cross-references Four Seasons 92375 for the same application.

What It Helps Address

• Hard starting caused by worn spark plugs
• Rough idle from weak or inconsistent spark output
• Misfire conditions related to electrode wear
• Reduced throttle response from degraded ignition performance
• Service intervals where OE-style spark plug replacement is required

Installation Notes

• Verify vehicle-specific gap requirements before installation; listed applications call for .032 inches on some Chrysler, Dodge, and Jeep models and .044 inches on Lincoln LS and Ford Thunderbird applications.
• Confirm thread diameter, reach, seat type, and terminal style match the original plug.
• Use proper spark plug socket size and torque specifications for the engine.
• Inspect ignition coils and plug wells during service to avoid repeat misfire concerns.

Quality Assurance

NGK manufactures spark plugs for a wide range of automotive applications and supplies original equipment programs across North America. The 92375 reflects that OE-focused engineering approach with materials and construction selected for durability and consistent operation.
