The K&N Engineering 81-0803 Air Oil Separator is designed to protect your engine and intake system from harmful blowby emissions. Constructed with a high-capacity reservoir, this oil separator effectively captures excess oil from crankcase vapors, helping to maintain optimal engine performance and prevent power loss caused by oil contamination. Its efficient design ensures that engine components stay cleaner, reducing the risk of sludge buildup and potential damage over time. Installation is straightforward, taking approximately 30 minutes with basic tools, and it features factory-style hose connections for quick, secure attachment and removal. The unit replaces the factory crankcase line, allowing for flexible mounting in your engine bay at a convenient location. Maintenance is simple, with no tools needed to check or empty the oil reservoir, making routine upkeep hassle-free. Engineered specifically for Dodge Challenger and Charger models equipped with a 6.2L V8 engine from 2015 to 2023, this separator guarantees a precise fit and reliable operation. Backed by K&N*s No-Hassle Lifetime Limited Warranty, it offers long-term protection and performance assurance for your vehicle.
