What It Is Used For
- Hard starting caused by worn or fouled spark plugs
- Rough idle and inconsistent combustion
- Misfire conditions related to weak spark delivery
- Reduced throttle response from degraded ignition performance
- Maintenance replacement on vehicles calling for NGK 95159 or FR6BHX-S
Installation Notes and Tips
- Verify the vehicle-specific gap before installation; listed applications vary by model and year.
- Some fitments require a twin-spark or dual-plug setup, including certain Mercedes-Benz and Maybach models.
- Use the notes for each application, such as 0.028, 0.032, 0.040, 0.044, or 0.050 inch gap requirements where specified.
