Product Details

NGK Laser Iridium High Ignitability spark plugs are engineered for OE replacement use where precise ignition performance matters. The iridium tip on NGK 92411 provides strong wear resistance, while the platinum ground electrode tip helps maintain consistent spark characteristics over time. The copper core and pure alumina ceramic insulator are used to manage heat and support reliable operation under daily driving conditions. This part number is also identified as DILKAR8P8SY and cross-references Honda/Acura OE numbers 12290-6A0-A01 and 122906A0A01 for the same application.

Compatible With 2023-2025 Acura Integra, N/A; 2022-2025 Acura MDX, N/A; 2019-2025 Acura RDX, N/A; 2021-2025 Acura TLX, N/A; 2018-2025 Honda Accord, N/A; 2022 Honda Civic, N/A; 2025 Honda Civic, N/A; and 2023-2025 Honda CR-V, N/A. For drivers searching for an NGK 92411 spark plug for Honda Accord, Honda Civic, or Acura RDX applications, this OE-style plug matches the high ignitability specification listed for those vehicles.

What It Helps Address

• Hard starting or inconsistent ignition performance
• Misfire concerns related to worn spark plug electrodes
• Rough idle caused by degraded spark quality
• Reduced combustion efficiency from aged plugs
• Service replacement needs on high-ignitability OE applications

Installation Notes

Verify engine code and OE spark plug specification before installation. The plug is pre-gapped at 0.030 in. and uses a flat seat with a non-removable nut terminal. Follow the vehicle service manual for torque specification and replacement interval guidance. For Acura MDX, Honda Accord, and Honda CR-V applications, confirm the OE high-ignitability requirement before ordering NGK 92411.

Quality Assurance

NGK manufactures this Laser Iridium line to OE standards and tests it for durability and consistent performance in approved applications. The design combines iridium, platinum, copper core, and ceramic materials to support dependable ignition service in modern Honda and Acura engines.
