Coltec Pro Intake Hose High Flow Nissan Navara STX550/Pathfinder Ti-550 V6

Description

Overview

The Coltec Pro High Flow Intake Hose Kit is engineered to replace the restrictive factory rubber hose found between the turbocharger inlet and airbox on the Nissan Navara STX550 and Pathfinder Ti-550. Designed from premium 5-ply reinforced silicone, this upgrade delivers exceptional durability and improved airflow for enhanced throttle response and turbo efficiency.

By minimizing flex and heat soak under boost, this intake hose allows your 3.0L V6 Turbo Diesel engine to breathe freely — improving spool-up speed, mid-range torque, and overall throttle performance throughout the rev range. Ideal for both tuned and factory vehicles, it’s a simple yet effective upgrade built to outperform OEM components.
