Mopar Performance 4627636AA PCV Seal for 6.4L HEMI V8

The Mopar Performance 4627636AA is a genuine OEM PCV (Positive Crankcase Ventilation) seal designed specifically for 6.4L HEMI V8 engines. This critical seal creates a leak-proof connection between the PCV system and the intake manifold, ensuring proper crankcase ventilation and preventing oil vapor leaks.

Key Features:

• Genuine Mopar OEM quality ensures exact fit and reliable performance
• Designed for 6.4L V8 HEMI upgrade HD engines and 6.4L heavy duty V8 HEMI with MDS (Multi-Displacement System)
• High-quality materials resistant to oil and heat
• Prevents vacuum leaks in the crankcase ventilation system
• Essential component for maintaining proper emissions control

Important Note: This seal is not included with long block engine install kits and must be ordered separately when performing engine installations or PCV system maintenance.

The PCV system plays a vital role in your HEMI engine by recycling crankcase vapors back into the intake manifold, maintaining proper crankcase pressure, and reducing harmful emissions. A properly functioning PCV seal ensures this system operates efficiently, preventing oil consumption issues and maintaining optimal engine performance.
