We want to ensure that you always purchase an authentic SM Motorenteile product. That is why our products are fitted with a counterfeit-proof label. Please use the security features listed below to verify the authenticity of your SM engine part, then follow the instructions provided. Both our current and previous labels are valid and indicate an authentic product. Each package carries a hologram label. At the bottom of the hologram, you will find a 16-digit code. The last three digits of this code also appear on the right-hand side of the hologram. They must match. To verify authenticity, please enter the 16-digit code from your label in the field above. Your product will then be checked automatically and the result will be displayed.
