The Vauxhall Vectra 2.0 DTI Silicone Turbo Intercooler Hose Upgrade is a direct-fit replacement for the factory rubber intercooler hose, designed to provide enhanced durability, heat resistance, and reliability in demanding conditions. Manufactured using premium-grade silicone with multiple layers of polyester braid reinforcement, the hose delivers improved pressure stability and resistance to oil mist, vibration, and heat compared to OEM hoses. With a 40 mm internal diameter, the hose is engineered to operate across a temperature range of -50°C to +220°C (with peaks up to +250°C), ensuring consistent performance in both daily driving and high-demand applications. Built to SAE J20 R3 standards, this upgrade maintains efficient airflow while offering long-term service life in turbocharged diesel systems.

Key Features:

• Application: Direct-fit silicone turbo intercooler hose upgrade for Vauxhall Vectra 2.0 DTI.

• Internal Diameter: 40 mm for correct intercooler system fitment.

• Material: High-grade silicone inner and outer layers for resilience and heat resistance.

• Reinforcement: Polyester braid for stability under boost pressure.

• Construction: 3–4 ply reinforced wall with smooth bore for efficient airflow.

• Operating Temperature: -50°C to +220°C (peak +250°C).

• Working Pressure: Up to 5.5 bar (size dependent).

• Bursting Pressure: Typically 3x working pressure for added safety.

• Standard: SAE J20 R3 compliant.

The reinforced silicone construction offers far greater durability than OEM rubber hoses, which are prone to cracking, swelling, and heat-related degradation. The multi-ply structure ensures dimensional stability under boost pressure, while the smooth internal bore supports efficient airflow with minimal turbulence. Resistant to oil vapours, ozone, and environmental wear, the intercooler hose upgrade ensures reliable performance even under prolonged thermal cycling and vibration. Its direct-fit design ensures straightforward installation without modification, making it suitable for both maintenance replacements and performance-focused upgrades.

Applications include standard road use, performance tuning, and preventative maintenance for Vauxhall Vectra 2.0 DTI turbo diesel engines. The silicone turbo intercooler hose upgrade is widely used by enthusiasts, workshops, and performance specialists seeking a durable, heat-resistant, and long-lasting solution to replace the original factory hose.
