Counterfeits are real serious problem for famous company’s now of days. It has hit all industries. Airline, drug, heavy equipment automotive and the list goes on. It even effects the price of the real parts, because company’s spent billions on the initial leg work tracking the counterfeits down before the case is turned over to law enforcement. Then little can be done if they come from third world countries. Speaking of nozzles the US Navy a few years back ended of with over a thousand of them. The Air Force, Navy and major Airlines got hold of counterfeit bolts that hold the jet engines on. I try to avoid any product with a price too good too be true( 30% or more lower then any other seller.
