The best way to protect yourself is to buy your products from authorized or reputable distributors or retailers. Although they can occasionally get fooled too, they are much more likely to make sure you can exchange the phony for a legitimate part. If you find or suspect counterfeit products or have any other intellectual property concerns, contact the legitimate manufacturer to alert them of your suspicions.
The industry must be united in refusing to accept fakes. I don't have to tell you that safety is the most critical aspect of our industry. We simply cannot compromise our commitment to ensuring that the products we provide and the vehicles they are equipped in are safe. Let's not let the crime of the 21st Century endanger our operators and the motoring public.
