Counterfeit spark plugs in circulation
The number of counterfeit branded products, which are mainly offered on online platforms, is growing in the aftermarket. Spark plug manufacturer Denso warns of the consequences for manufacturers, retailers, workshops and drivers. A workshop tip on the Denso website helps you distinguish between an original and a fake. The differences can be seen, for example, in the packaging, the appearance of the candle and the technical features. The problem for the user: In many cases, counterfeits are made from inferior materials that have not been tested for safety. This can lead to a significant drop in performance under heavy acceleration or load. If these plugs overheat, they will melt and cause serious engine damage. The counterfeits are usually noticeable because of their extremely low prices compared to branded products. The indication of origin can also be an indication of a counterfeit, as original Denso spark plugs are only produced in Japan, Indonesia, China and the USA.
