Engineered to meet stringent OEM (Original Equipment Manufacturer) specifications and utilized on global automaker assembly lines, KIEK Spark Plugs deliver optimized, stable ignition across diverse operational conditions. Featuring a high-alumina ceramic insulator, these plugs provide exceptional thermal shock resistance and extended service durability.

The negative ground electrode utilizes premium platinum alloys with minimal electrical resistance to shape a high-energy spark gap for full, clean fuel combustion. Encased in a heavy-duty steel shell with thick nickel plating, the plug effectively prevents thread seizure and corrosion. Integrated internal resistor technology eliminates RFI noise, safeguarding sensitive onboard electronic devices. Designed for carbureted, fuel-injected, and CNG engines, these spark plugs maintain peak ignition efficiency up to 50,000 kilometers under the license and technical supervision of DAkkS GERMANY.

Main Functions of Engine Spark Plugs:

• Air-Fuel Ignition: Generates a high-voltage electrical spark across the electrode gap at precise valve timing intervals to ignite compressed air-fuel mixtures.
• Thermal Shock & High-Pressure Endurance: Withstands combustion chamber peak pressures and instantaneous thermal spikes up to several thousand degrees Celsius.
• High-Voltage Electrical Insulation: High-purity alumina insulator guides thousands of volts from ignition coils directly to the tip without flashover or energy leakage.
• Heat Dissipation: Transfers excess combustion chamber heat through the threaded steel shell into the cylinder head cooling jackets to prevent pre-ignition and engine knock.

1. Installation Guidelines:

• Verify Specifications: Always select the correct heat range, thread reach, hex size, and electrode configuration for your engine code.
• Check Electrode Gap: Measure and calibrate the electrode gap using a feeler gauge according to manufacturer specifications prior to installation.
• Clean Cylinder Head Well: Blow compressed air around spark plug wells before removal to prevent dirt or debris from entering the cylinder.
• Hand-Thread First: Always hand-thread the spark plug into the cylinder head to ensure correct thread engagement and prevent cross-threading on aluminum heads.
• Torque Specifications: Tighten using a torque wrench to manufacturer-recommended torque values. Over-tightening damages aluminum head threads, while under-tightening causes compression loss and thermal overheating.

2. Failure Symptoms & Replacement Schedule:

• Symptoms of Worn Spark Plugs: Engine misfiring, sluggish acceleration, poor fuel economy, rough idling, hard starting in cold weather, increased exhaust emissions, or a check engine light illumination.
• Replacement Schedule: These spark plugs offer peak performance up to 50,000 km. However, adhere to regular vehicle maintenance schedules or replace earlier if operating under severe conditions (e.g., heavy city traffic, extreme cold/heat, or low-quality fuels).

3. Replacement & Non-Repairability:

Spark plugs are consumable components that cannot be repaired once electrodes suffer material erosion or ceramic degradation. Always replace spark plugs as a complete set to ensure balanced ignition timing across all cylinders.
