See If This Product Fits Your Vehicle
The Sinister Diesel Billet Catch Can Kit is the perfect upgrade to protect your 6.7L Cummins from oil blow-by and intake contamination. Designed to capture oil mist, vapor, and other contaminants before they re-enter your intake system, this kit helps maintain optimal airflow and combustion efficiency while keeping your turbo and intercooler clean.
Oil residue inside the intake or intercooler can reduce thermal transfer and cause the turbo’s compressor wheel to become unbalanced, shortening its lifespan. The Sinister Diesel Catch Can prevents these issues by separating oil and contaminants from the crankcase gases before they circulate through your engine. The result is better reliability, smoother performance, and longer-lasting components.
Built from CNC-machined billet aluminum, this catch can features fully baffled internals and a high-flow design that keeps crankcase pressure under control while efficiently capturing contaminants. The can is easy to inspect and drain without removal, and it mounts neatly to the frame rail using the supplied hardware.
