As a matter of fact, the most commonly counterfeited parts are maintenance and high-vol- ume items including but not limited to clutch discs, clutch facings, clutch covers, oil/fuel/air filters and spark plugs that are so called consumable parts being made available on the market like many others.Among such counterfeit parts, you may often find smartly copied and packaged items by using high-tech meanswith only subtle differences that cannot be identified by most customers by appearances only. Customers may think what they have bought is genuine. Such imitations, however, are often potentially hazardous because of their hidden dangers since imitation parts are inferior in quality and performance to genuine parts.Now, we would like to present how to distinguish differences between genuine and imitation parts by givingexamples with photographs that they look very much alike by appearances. As a matter of fact, it would be very difficult for distributors to tell which is which.
