URO 079103209AK Crankcase Breather Hose

The URO 079103209AK is a replacement crankcase breather hose designed for Audi and Volkswagen vehicles equipped with 4.2L V8 engines. This hose is a critical component of the positive crankcase ventilation (PCV) system, routing crankcase vapors from the engine block back into the intake system for combustion.

Key Features:

• Direct replacement for OEM part number 079103209AK
• Manufactured to meet or exceed original equipment specifications
• Constructed from durable rubber compound resistant to oil and heat
• Helps maintain proper crankcase pressure and ventilation
• Prevents oil leaks and maintains emissions compliance

Over time, crankcase breather hoses can deteriorate from constant exposure to heat, oil vapors, and engine vibration, leading to cracks, hardening, or complete failure.
