Honda Fit Civic City Accord Iridium Spark Plug IZFR6K-11S 9807B-561BW Stable Output

When your Honda Fit, Civic, City, or Accord experiences idling instability, acceleration hesitation, cold-start difficulty, or noticeably higher fuel consumption, the original spark plug may be aged and ignition energy insufficient for complete combustion. This iridium spark plug reliably releases high-energy sparks for stable combustion, improving throttle response, reducing fuel consumption and carbon buildup. Fits most Honda models from 2000 onwards; OEM numbers 9807B-561BW and IZFR6K-11S. Install with a torque wrench to manufacturer torque to avoid thread damage or leaks from over-loosening.
