K&N Catch Can Oil Separator – 2011-2021 Dodge Challenger 6.4L V8 (and compatible 6.4L HEMI models)

The K&N 81-0801 Catch Can Oil Separator is a high-quality billet aluminum oil catch can designed to capture harmful oil vapors and blow-by before they contaminate the intake tract and reduce performance in your 6.4L HEMI engine. Specifically engineered for the 2011-2021 Dodge Challenger 6.4L V8, this separator prevents carbon buildup, maintains octane levels, and protects your engine for cleaner combustion and sustained power. It features a generous 6 oz reservoir that is easy to drain and mounts cleanly using factory-style connections.

  • 6 oz Capacity – Large reservoir reduces draining frequency while effectively trapping oil mist
