Description
Replacement spring and cap kit for rebuilding the crankcase breather on BMW M57 engines used in the 335d and X5 35d.
Worn breather components can allow excess crankcase vapors into the intake, accelerating carbon buildup and increasing the risk of DPF clogging. Replacing these parts helps restore proper crankcase ventilation and protect downstream components.
