How to Identify the Model of 3008 NGK Spark Plug?
3 Answers
3008 NGK spark plug model identification method: The first letter at the beginning represents the thread diameter of the spark plug. For example, 'B' represents a 14mm thread, 'C' represents a 10mm thread, 'D' represents a 12mm thread, and so on. The spark plug, commonly known as the sparking plug, functions to discharge the high-voltage pulse electricity delivered by the high-voltage wire (spark plug wire), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others. The spark plug, in coordination with the ignition system and fuel supply system, enables the engine to perform work, collectively determining the engine's performance to a significant extent.
I've been driving for over 20 years and found the most reliable method is to check the 3008's vehicle manual, which is usually in the glove compartment. The maintenance section clearly lists the original spark plug model, such as NGK LFR6AIX-11. If the manual is missing, remove the old spark plug to check - NGK products always have the model engraved on the metal casing. Take a photo with your phone or jot it down in a notebook for future reference. Choosing the wrong model is no small matter; it could lead to engine failure or increased fuel consumption. I once tried a cheaper, incompatible one and ended up with severe engine shaking. It's best to regularly record spark plug data for easier future replacements. Stay vigilant during maintenance to avoid last-minute hassles.
As a young car enthusiast who prefers using apps, I recommend checking online for the most convenience. The NGK official website has a parts lookup tool where you can enter 'Peugeot 3008' and the year, and the recommended model will pop up immediately. Alternatively, you can download auto parts apps like PartsBox, which provide comprehensive vehicle model information. The spark plug body also has engraved numbers—last time I DIYed, I removed it and read the code, such as LTR5IX-11. Forums like Autohome also have owners sharing experience posts. When buying new spark plugs, match the numbers to avoid model confusion affecting your vehicle's performance. With regular practice, it becomes second nature.
