Picture this: you're hauling a full trailer up a steep grade, and your 6.7L Cummins is humming along perfectly. But under the hood, crankcase pressures are pushing oil-laden vapors right into your intake tract. Over thousands of miles, that buildup turns into a sludgy mess on valves, turbos, and intercoolers, robbing efficiency and forcing early repairs.
Modern 6.7 Cummins ISB engines produce blow-by gases—normal combustion leftovers mixed with oil mist. Without proper filtration, this stuff recirculates, leading to carbon deposits, reduced airflow, and even EGR system clogs. Truck owners know the drill: warning lights, derates, or worse, a turbo failure that sidelines your rig for weeks.
This crankcase ventilation filter steps in as a drop-in replacement for OEM numbers like CV52001, 68002433AB, 4936636, and 904-418. Crafted to exact specs, it captures oil aerosols and particulates before they reach the intake. No modifications needed—just unbolt the old one during your next oil change and bolt this in. Fits all 2008-2021 Dodge Ram 2500, 3500, 4500, and 5500 models with the 6.7L diesel.
Expect cleaner combustion from day one. That means better throttle response, slight fuel economy gains, and less frequent deep cleans. Your turbo spins freer without oil fouling, extending its life considerably. For fleet operators or daily haulers, it's peace of mind—fewer breakdowns, lower maintenance costs. I've swapped these on my own Ram, and the difference in oil residue on the intake boot was night and day after 10,000 miles.
Replace every 30,000-50,000 miles or sooner if you're in dusty conditions or pushing hard. Tools needed: basic wrenches and maybe a ratchet strap for access. Takes under 30 minutes solo. Pair it with fresh oil and an air filter for peak performance. Whether you're wrenching on your work truck or weekend warrior rig, this filter delivers reliability you can count on.
Don't let hidden contaminants shorten your Cummins' life. Grab this CCV filter and keep your Ram breathing right.
