There are many models and items of auto parts for one vehicle. Some items are so similar that it is easy to make mistakes when purchasing. How can we ensure that customers will not buy unfit products when they buy? Now let us take our major product - ignition coil - as an example to introduce our product confirmation method and steps.
The first method is to determine by the OEM numbers of the product. Sometimes a product corresponds to a specific OEM number. But in most cases, several or even dozens of OEM numbers correspond to the same item of product. As long as the customer can provide us with the CORRECT OEM numbers, we can accurately determine that product very quickly. For example, the following 9 different OEM numbers correspond to one ignition coil which is universal each other. See picture 1.
Sometimes, our customer can’t provide us the correct OEM numbers, because there is no OEM numbers on the original product he has and he does not know where to get the correct OEM numbers. In this case, we will ask the customer to send us multi-angle pictures of the product, including the full picture of the product, picture of connector, picture of rubber sleeve, etc.
How to accurately identify the matching product, the connector is a key point. Connectors come in a variety of shapes, including rectangular, square, round, triangular, and more. There are 2 pins, 3 pins, 4 pins, or more pins in the connector of an ignition coil. The connecter has the difference of the opening facing forward and the opening sloping upward. The size, quantity, and position of the buckles on the connectors of ignition coils are not exactly the same. Some are on the upper part, some are on the lower part, some are on the left, and some are on the right of the connector. Some ignition coils are fixed with grooves instead of buckles on the connectors.
The next thing we have to pay attention to is the position of the ignition coil mounting hole. Some are located behind the top of the ignition coil, some are on the left, and some are on the right. We pay attention to the shape, size, color and length of the ignition coil rubber sleeve. We also look at how the shape of the rubber boot meets the coil stem on the very similar products.
When it is not possible to accurately determine whether the product belongs to that type of vehicle based on the above characteristics, it can also be determined based on the special marks on the product's appearance. For example, most of Toyota or Nissan vehicles use 1 circle, 2 circles or 3 circles to distinguish the rod shape on their ignition coils. And the position, thickness, or spacing between the circles are not exactly the same. See picture 2.
After we complete the above identification, we can accurately determine the general products. However, in some cases, there are no OEM numbers on the products, and the product parameters are exactly the same, only the color of the connectors and the length of the fins of the rubber sleeve are somewhat different. Under the premise that we cannot make an accurate judgment, we need our customer to send us the original sample(s) for further confirmation. See picture 3.
We have become very familiar with our products over the years. In most cases, we can quickly and accurately determine whether the customer's needs match our corresponding products. When we send the Proforma Invoice to our customer, we will also send an Excel document with detailed parameters such as product image(s), OEM numbers, and vehicle applications for his careful checking. We will not let go any doubts, and we will not allow customers to make payments until both parties have confirmed they are correct. So, you can rest assured that all the products you are buying are fit your vehicles.
