X4XZ Air Intake Hose for Nissan Frontier 4.0L V6 (2005–2019) — Direct-Fit, Reinforced Rubber

This X4XZ 696-009 intake hose is a purpose-made replacement for the OEM part (replacement part number 16576EA200). Manufactured to match original equipment specifications, the hose links the air filter box to the throttle body to ensure clean, measured airflow into the engine. It’s designed for drivers who need a durable, cost-effective fix to resolve intake leaks, check-engine triggers, or drivability issues caused by a worn or cracked hose.

How does this hose affect engine performance?

A sealed, undamaged intake hose maintains correct air metering and reduces unmetered air entering the engine. When the hose is compromised, you can see rough idle, hesitation under load, or a triggered check engine light. Replacing the damaged hose helps the engine control unit read accurate intake volumes and restores predictable throttle response.

• Direct connection between airbox and throttle body for consistent airflow.
• Prevents vacuum leaks that cause erratic idling or poor acceleration.
• Helps maintain fuel economy by preserving correct air/fuel ratios.
