If you're maintaining Caterpillar C7, C12, C13, C15, or C16 engines, this crankcase ventilation filter is exactly what you need to keep things running smoothly. It directly replaces those common OEM numbers like 380-5840, 296-8325, CV15008, and CV50304. This isn't some generic knock-off either - it's manufactured to meet original equipment standards and goes through rigorous factory testing to ensure proper performance. You'll find it fits a bunch of heavy-duty applications including Freightliner CONDOR, CL112, CST120, M2 112 models from 1995-2012, plus Western Star 4900, 6900 series, and Peterbilt 387 or Kenworth W900 trucks with compatible engines. It also works with Cummins N14 engines if that's what you're running. The filter comes brand new in the package, ready to install. Keeping your crankcase ventilation system working properly is crucial for engine health and emissions control - this filter helps trap those blow-by gases and contaminants before they can cause problems. Whether you're a fleet manager, independent trucker, or repair shop, having the right filters on hand prevents downtime and keeps your equipment running reliably. Just pop this in during your regular maintenance and you're good to go for many more miles on the road!
