This aftermarket component is engineered for the 7.3-liter Power Stroke diesel engine. It facilitates the removal of the closed crankcase ventilation system, which redirects crankcase gases back into the engine’s intake. The kits typically consist of a replacement filter, hoses, and fittings designed to vent these gases directly into the atmosphere.
Its implementation is often driven by the desire to mitigate oil buildup in the intake manifold and intercooler, potentially improving engine performance and longevity by preventing the recirculation of oil vapor. Historically, such modifications have been implemented in performance-oriented applications or where regulatory compliance is not a primary concern.
