I purchased the OEM Fleetguard CCV filter on Amazon exactly a year ago for $54.99. Installed it last week. I like to keep ahead on maintenance items, so searched around today for another. Price has more than doubled and Amazon is out of stock. Lots of knock-off filters out there much cheaper. However, noticed this from a Cummins Filtration email I receive regularly.
"Cheap crankcase ventilation systems can’t take the heat"
If your crankcase ventilation system includes cheap polypropylene media, it can melt under high temperatures. That not only eliminates its efficiency, but the melted material may clog the drain line or block other ports in the engine. This could lead to catastrophic damage for your engine.
