⚡ At a Glance
- • Airflow Performance: Reroutes crankcase vapours to maximise airflow and reduce unnecessary pressure build-up
- • Best for: Owners of 2007.5–2017 Cummins 6.7 engines seeking cleaner crankcase operation
- • Not ideal for: Engines outside the specified Cummins 6.7 fitment or non-matching part numbers
Engineered specifically for 2007.5–2017 Cummins 6.7 fitment with matching part numbers. Built from materials resistant to oil, heat and wear for consistent filtration performance.
Smoother Engine Breathing - Thanks to the reroute breather design
Reroute passages channel crankcase vapours away from the intake path, increasing airflow and lowering internal crankcase pressure. The design aims to manage vapour flow so pressure spikes are minimised during load changes.
Improved breathing reduces stress on seals and gaskets, helping maintain steady combustion under load and lowering the chance of pressure-related leaks.
Cleaner Crankcase, Lower Emissions - With effective filtration and vapour management
Filtration captures oil vapours and particulates before rerouting, preventing re-entry into the intake stream. Controlled vapour flow reduces blow-by returning to the engine.
Reduced blow-by keeps the crankcase cleaner and helps lower emissions, supporting longer-lasting components and easier routine maintenance.
Durable, Vehicle-Specific Fit - With oil-, heat- and wear-resistant construction
Components are made from materials specified to resist oil, heat and mechanical wear, and the kit matches part numbers 3AD819728A, 3C1819728F and 3AB819728A for fitment. The package includes the necessary parts for installation.
Robust build and direct-fit compatibility minimise the chance of misfit and reduce the need for repeat replacements, allowing confident DIY installation for compatible owners.
