Keep your twin turbo straight-six running clean and consistent with this CTS Turbo catch tank system. Designed to intercept blow-by and oil mist before it reaches the intake tract, this PCV solution helps reduce intake valve deposits on direct-injection N54 engines, supports stable idle, and preserves performance over the long term. If you are searching for an N54 oil separator, PCV catch tank, crankcase breather kit or engine oil mist separator, this is a proven, vehicle-specific package that installs neatly and works brilliantly.

We have fitted and run this kit on our own builds and customer cars. Feedback is consistently positive on fit, finish and real-world results, whether for daily use, spirited B-road driving or track days.
