Old rule of thumb, once one goes the others will follow at some point. Just my 2 cents worth.
But yes you can just change the one injector if thats your only option.
I am not sure about yours, but mine new OEM from BMW were about $350 each, I ended up getting new/used ones for $75 each

Hi, I'm counting myself lucky to stumble upon your post because I'm running into the exact same situation as you have.
I also drive a E90 335xi ('09 sedan) and my injectors are due to be replaced because they are leaking and they are low index #s. I'm applying that rule of thumb and I'm preparing to have all 6 upgraded to index 11 or 12, any chance you could please refer me to your supplier?
