This billet aluminum PCV valve and cover kit is a direct upgrade for N54 twin turbo engines, designed to solve one of the platform’s most common weak points. Factory PCV components are prone to cracking, leaking, and allowing excessive crankcase pressure—leading to oil loss and inconsistent performance.

This upgraded solution replaces failure-prone factory components with precision-machined aluminum and a high-temperature sealing system to maintain proper crankcase ventilation under both street and aggressive driving conditions.

Key Benefits

• Reduces crankcase pressure buildup
• Helps prevent oil leaks and blow-by issues
• Improves long-term reliability under heat and boost
• Direct-fit replacement for factory PCV components

Construction & Design

• CNC-machined billet aluminum valve and cover
• Heat-resistant fluoroelastomer O-ring for secure sealing
• Anodized surface for corrosion resistance and clean engine bay appearance
• Precision-machined for accurate fitment and durability
