About the Citroen Relay Peugeot Boxer Turbo Intercooler Hose

This replacement turbo intercooler hose has been specifically designed to fit multiple commercial vehicle platforms sharing common engine architecture. Suitable for Citroen Relay models from 2016 onwards fitted with 2.0 and 2.2 BlueHDi engines (DW10 and DW12 engine codes), Peugeot Boxer vehicles from 2016 onwards with the same BlueHDi powerplants, Fiat Ducato models from 2018 onwards equipped with the 2.2 Multijet engine, and Vauxhall Movano vans from 2021 onwards featuring 2.2 Turbo D and CDTI variants, this component represents a direct OE replacement with enhanced material properties.

The OE part number references include 1686705780, 1638153280, 1617244480, 1622958180, 46863152, 1398849080, and 1379292080, ensuring accurate fitment across the entire range of compatible vehicles. Our SKU reference 1606660380 guarantees you receive the correct left-hand side application for your vehicle’s turbocharger-to-intercooler routing.

Why Choose Stainless Steel for Your Turbo Intercooler Hose?

Factory-fitted turbo intercooler hose assemblies are typically manufactured from rubber or flexible synthetic materials with metal connectors. Whilst these components perform adequately under standard operating conditions, they can deteriorate over time due to constant exposure to heat cycling, vibration, oil contamination, and the corrosive effects of road salt and environmental pollutants. Commercial vehicles operating in demanding conditions—such as frequent motorway driving, heavy payload transportation, or year-round professional use—place additional stress on these components.

Stainless steel construction offers significant advantages over conventional materials. The inherent strength of stainless steel means the pipe maintains its structural integrity even under elevated boost pressures, preventing the expansion and flexing that can occur with rubber hoses. This rigidity ensures consistent airflow to the intercooler, maintaining optimal charge air temperatures and preserving engine efficiency.

Additionally, stainless steel resists corrosion, eliminating the perishing and cracking that eventually affects rubber components, particularly in the engine bay environment where temperature fluctuations are extreme.

Performance Benefits of Upgrading Your Turbo Intercooler Hose

Installing a stainless steel turbo intercooler hose delivers measurable improvements in several key areas. Firstly, the smooth internal bore and rigid construction reduce turbulence and pressure drop between the turbocharger compressor outlet and the intercooler inlet. Even marginal reductions in pressure loss translate to improved throttle response and more efficient boost delivery throughout the rev range.

Secondly, the enhanced durability of stainless steel construction eliminates a common failure point. Commercial vehicle operators cannot afford unexpected downtime caused by split intercooler hoses, which can lead to dramatic power loss, increased fuel consumption, and potential engine damage if the issue goes undetected. The longevity of stainless steel components provides peace of mind and reduces long-term maintenance costs.

Thirdly, the heat management properties of stainless steel help maintain lower intake air temperatures. Whilst the intercooler performs the primary cooling function, reducing heat transfer from the turbocharger to the charge air before it reaches the intercooler contributes to overall thermal efficiency. Cooler, denser intake air contains more oxygen molecules per unit volume, supporting more complete combustion and improved power output.

Installation Considerations for Your Turbo Intercooler Hose Replacement

Replacing the factory turbo intercooler hose with this stainless steel upgrade is a straightforward procedure for competent home mechanics or professional workshops. The component is engineered as a direct replacement, utilising the existing mounting points and connection interfaces without requiring modification to surrounding components. Standard hand tools are typically sufficient, though depending on vehicle-specific access, removal of auxiliary components may be necessary to provide adequate working clearance.

Before installation, ensure all mating surfaces are thoroughly cleaned to prevent debris from entering the turbocharger or intercooler system. Use appropriate sealants or gaskets as specified by the vehicle manufacturer, and torque all fasteners to the recommended specifications to prevent leaks under boost pressure. Following installation, a thorough inspection for leaks during initial operation is essential—even minor boost leaks can significantly impact performance and fuel economy.

Compatibility and Application

This left-hand side turbo intercooler hose is precision-manufactured to meet the exacting specifications required for the following applications:

• Citroen Relay: 2016 onwards, 2.0 BlueHDi and 2.2 BlueHDi engines (DW10 and DW12 engine codes)
• Peugeot Boxer: 2016 onwards, 2.0 BlueHDi and 2.2 BlueHDi engines (DW10 and DW12 engine codes)
• Fiat Ducato: 2018 onwards, 2.2 Multijet diesel engine
• Vauxhall Movano: 2021 onwards, 2.2 Turbo D and 2.2 CDTI engines

Always verify your vehicle’s engine code and model year before ordering to ensure compatibility. The multiple OE reference numbers covered by this component reflect the shared platform engineering across the PSA Group, Stellantis, and affiliated manufacturers.

Frequently Asked Questions

Will this turbo intercooler hose improve my vehicle’s performance?

Yes, the stainless steel construction reduces pressure loss and maintains consistent boost delivery, resulting in improved throttle response and more efficient turbocharger operation compared to deteriorated or flexible factory components.

Is this component suitable for vehicles with remapped ECUs?

Absolutely. The robust stainless steel construction is ideal for vehicles running increased boost pressures from ECU tuning, providing the structural integrity necessary to handle elevated performance levels without expansion or failure.

How long will this stainless steel pipe last?

With proper installation and normal operating conditions, stainless steel intercooler pipes typically outlast the vehicle itself, offering significantly greater longevity than rubber alternatives which may require replacement every 5-7 years depending on usage.

Does this replace both left and right side pipes?

No, this product is specifically the left-hand side turbo intercooler hose. If your vehicle requires both sides replacing, please ensure you order the corresponding right-hand component separately.
