Cracked Intake Hose Causing Vacuum Leaks or Rough Idle?

Replace One of the Most Common MK4 Volkswagen Intake Failures.

The factory engine air intake hose connects the air filter housing to the intake system, ensuring smooth and properly metered airflow into the engine.

Over time, exposure to:

• engine heat
• oil vapors
• vibration
• aging rubber
• repeated heat cycles

can cause the original intake hose to:

• crack
• split
• collapse
• leak unmetered air

A damaged intake hose may cause:

✔ Rough idle
✔ Vacuum leaks
✔ Check engine light
✔ Lean air/fuel codes
✔ Poor throttle response
✔ Intake whistling or hissing noise
✔ Reduced engine performance

This OEM-style engine air intake hose is designed to restore proper airflow and eliminate intake system leaks.

Manufactured from reinforced heat-resistant rubber, it provides reliable direct-fit installation for selected Volkswagen and Audi vehicles.
