| example the original spark plug (left) and fake (right) |
Create an NGK brand, the most obvious is the use of a plastic cap on the screw plugs. It was obviously fake products. For all the plugs that we produce none used a plastic cap on the screw. Even if there are material for the type of paper and even then Iridium, not standard.
In addition, another feature that can be distinguished is the subtlety of its form. Among them:
1 terminal nut
At the terminal nut, screw on the original spark plugs more sleek than the fake.
2 Part number
The writing part number on the original spark plugs neatly organized. While the false word can be thicker, or thinner and position are not neat.
3, Number in hexagonal
The original NGK spark plugs always have a production lot number at the hexagonal part that is not found in fake plugs.
4 Materials plugs
The original spark plug metal shell made of strong steel and heat resistant. With the process of plating Cr3, the original spark plug corrosion resistant and the color will not fade even if stored longer.
5. Ring gaskets spark plugs
Because of its design origin, gaskets / washers fake plugs easily dislodged. While the position of the ring in the original spark plugs are designed to be more difficult regardless. When detached, the NGK claims if the ring is not going to be put back on the spark plugs.
6 Electrode spark plugs
Construction tip of the electrode, the spark plug gap and connecting the original very neat. So it is likely to break off and damage the engine would not exist.
Furthermore, this friendly guy also explained briefly about the dangers of fake spark plug applications. The use of fake plugs are very harmful, even can damage the engine. For example, a metal material on the fake spark plug electrode tip easily broken. The fracture can enter the combustion chamber and piston-hit join. As a result, the piston can be damaged, and even spread to other components such as valves and others.
