Filter element signature method:Take a look at the filter material，The main filter material of air filter core is filter paper. Nowadays, the filter paper of air filter core mainly USES domestic paper and imported paper. Both domestic and imported paper have good filtration performance, and the inferior filter paper used by the fake filter element cannot prevent dust from entering the engine, thus affecting the normal operation of the engine.The color of the filter paper of the filter element of normal products is uniform, and the paper surface is relatively smooth.And the color of inferior filter paper is not uniform, the paper surface hair, the texture is very poor.Second, look at the colloid of the filter elementNowadays, the construction of the filter element is generally made of filter paper and rubber adhesive, and the glue of the real filter element is also different.The rubber of the filter element of the real product is of good quality and full of flexibility, while the rubber of the fake filter element is soft and of poor quality.
The easier way to distinguish is to fold the air filter core in half, and the filter core of the real product will return to its original state soon after it is released. However, due to the rubber quality problem, the fake filter core is not well bonded with the filter paper, and the mark of the middle part of the fold is obvious.
Additional: can pass a few mark, for example the line grain that imports, of course domestic also some go copy, but careful observation is different.
