Honda Fit / City / Civic / Jazz / Accord / CR-V spark plug SKJ16DR-M11 9807B-5515W

This KLP iridium spark plug SKJ16DR-M11 uses iridium electrodes, providing better wear resistance than factory nickel alloy; under normal conditions, service life can reach 80,000–100,000 km, about double the original. Resistance remains at 6 kΩ, ignition energy more uniform, reducing engine vibration and carbon buildup risk. Fits Honda Fit, City, Civ ic, Jade, and Accord, and many post-2000 models, with part number 9807B-5515W directly replacing SKJ16DR-M11. It ignites the air–fuel mixture, iridium electrode maintains longer spark intensity, and cold start and acceleration response are crisper than standard plugs. Installation is moderate; requires removing ignition coil and high-voltage wire; torque to factory torque; 26.5 mm thread length, M14x1.25; position fitment standard; ordinary repair stations can handle, but avoid over-tightening to avoid damaging cylinder head threads.
