For me its not about resistance these older m5 e60 injectors have been known to stick open and hydrolock damaging your engine, you are saving nearly $1000 dollars and thats not vs bmw pricing, asking me to check resistance on the old vs new is a complete waste of time, its flow rates that decline and the locking open is mechanical, and from past experience having them cleaned and flow tested is another waste as normally leads to dripping injectors and poor starting, so always fit new and put it to the top of any list! Forget testing old one you either choose to do it or you dont simples..
