宝马劳斯莱斯高压燃油泵 13517574440 0261520067 直喷油泵

This high-pressure fuel pump directly replaces original numbers 13517574440 and 0261520067; high compatibility for BMW and Rolls-Royce direct injection engines post-2000. Core function is to pressurize fuel to standard value, ensure precise atomization at the injectors, and maintain proper combustion. Replacing resolves acceleration weakness, starting difficulty, or idle shudder, especially noticeable when cold starts. If the car feels labored, fuel consumption rises, or the dashboard shows engine light, the pump may be aging and losing pressure; replace early to protect injectors.
