The K&N Engineering Air Oil Separator (Part No. 81-0801) is designed to protect your Dodge Challenger's engine and intake system from harmful blowby gases by efficiently capturing oil in a high-capacity reservoir. This innovative component prevents oil from entering the intake tract, which helps maintain optimal engine performance and reduces the risk of power loss or potential engine damage caused by oil buildup. Installation is straightforward, taking approximately 30 minutes with basic hand tools, thanks to factory-style hose connections that snap on and off easily. The separator replaces the factory line from the crankcase, allowing you to mount it conveniently within your engine bay for quick access and maintenance. The oil reservoir can be checked and emptied without tools, ensuring hassle-free upkeep and consistent performance over time. Built specifically for your vehicle, this separator is engineered to fit seamlessly and backed by K&N*s No-Hassle Lifetime Limited Warranty, offering durability and peace of mind for automotive enthusiasts. Whether enhancing engine longevity or ensuring cleaner intake air, this separator is an essential upgrade for serious Dodge Challenger owners seeking reliable blowby management. It is compatible with gasoline-powered engines and complies with Prop 65 regulations, ensuring safety and quality standards are met for responsible vehicle modifications.
