This air-oil separator is a critical component for maintaining engine efficiency in Porsche Boxster and 996/997 models. It captures residual gases and vapours from the crankcase, recycling them into the intake manifold for combustion, reducing emissions and ensuring smooth engine operation.

A failing separator can lead to excessive vacuum, drawing oil into the intake and causing blue-grey exhaust smoke. This high-quality replacement restores proper function, preventing performance issues and ensuring compliance with emissions regulations. Replace your faulty separator to keep your engine running clean and efficient.
