Bosch BMW B58 Gen 1 Direct Fuel Injector - Bosch 0261500541 / 13538625396 / 13537639990

Replacement high pressure fuel injectors, including sealing o-rings

All new turbocharged BMW engines use a direct fuel injection system which 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 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.
