All-new turbocharged BMW engines use a direct fuel injection system that directly injects fuel into the combustion chamber. This differs from a port injection system which injects fuel into the intake side of the engine through the intake manifold. Direct injection fuel systems operate at a significantly higher pressure than a conventional port injection fuel system. Due to the design, the engine really relies heavily on a properly operating fuel system. If your BMW is suffering from misfires or has a rough idle it can be due to faulty fuel injectors.

BMW has redesigned this fuel injector numerous times to address failure points. This injector is the most recent design. Due to this redesign, it is absolutely vital to inspect the index number on your existing fuel injectors. The index number can be found on the head of the injector after the BMW part number. An example of this is 13538616079-11 where "11" is the index number. Injectors with index 10 and lower have a different calibration and construction than injectors with an index of 11 or higher. Due to this difference injectors with 10 or lower cannot be mixed with injectors of 11 or higher and should not be installed in the same cylinder bank.
