BMW N55 EU5 Fuel Injector. I was going to fit this to my 2011 135i N55 but found that my fuel injectors was not my issue. I am including the brand new OEM decoupling element with this too. This is the OE Injector which means it’s the exact same as the one that came with your engine out the factory. This will fit a 2011 135i N55 and I can imagine it would fit 335i, X1 and X3 equipped with the N55 too. I don’t mind sending proof of purchase on the chat, I got the injector and decoupling element from FCP Euro, a well known and trusted American company with unlimited lifetime warranty.
