The BMW NGK "F8S" Flex Fuel Spark Plug is the next best thing for N54 N55 S55 engines running full E85.
- Iridium electrodes for high performance
- Shorter, less exposed center electrode (projection)
- Slightly colder heat range for better knock resistance and misfires
- Imported from BMW Germany, not typically found in the United States
- This NGK spark plug is an upgrade for N54 N55 or S55 engines running E85 and other blended fuels with more timing and higher boost. The center electrode height is shorter and better protected than the original plug. Running a slightly colder heat range leads to lower combustion chamber temperatures and resists knocking and misfires.
