Mopar Performance 5184806AD Air Make-Up Breather Hose OEM Replacement

The Mopar Performance 5184806AD is a genuine OEM air make-up (breather) hose designed as a direct factory replacement for the crankcase ventilation system. This hose plays a critical role in the engine's Positive Crankcase Ventilation (PCV) circuit by routing fresh air into the crankcase to equalize pressure and evacuate harmful blow-by gases—helping maintain engine efficiency, reduce oil consumption, and minimize emissions.

Key Features:

• Genuine Mopar OEM part — engineered to exact factory specifications for a precise fit and reliable, long-term performance
• Direct OEM replacement — restores original crankcase ventilation function and prevents pressure buildup that can cause oil leaks or seal damage
• Durable construction — manufactured from heat- and oil-resistant materials to withstand the harsh underhood environment
• No modification required — mounts to factory attachment points for a straightforward, hassle-free installation
• Part Number: 5184806AD

Replacing a cracked, brittle, or collapsed breather hose is essential to keeping the PCV system functioning properly. A failed breather hose can allow unmetered air into the intake, cause rough idle, trigger check engine lights, and accelerate engine wear. The Mopar 5184806AD ensures your engine breathes correctly and operates as designed.
