Racingline boost hose kit for VW Polo VI GTI/Audi A1 II 40 TFSI

Replace the soft, damage-prone factory rubber boost hoses on the VW Polo VI GTI (AW) 2.0 TSI engine with the Racingline kit. The kit is made from multi-layer, reinforced motorsport-grade silicone. Direct fitment provides a firmer accelerator pedal feel, more consistent boost pressure and a tidier engine bay.

Original rubber hoses can expand under load, especially on modified vehicles. This expansion causes boost pressure losses and poorer throttle response, and over time can also lead to cracks or complete hose failure. The Racingline kit retains its shape under pressure and helps maintain boost pressure between the turbocharger and engine.

Why upgrade the boost hoses?

On the 2.0 TSI engine in the Polo GTI, the factory hoses are exposed to high temperatures and high pressure. As boost pressure rises, the soft rubber expands outwards, resulting in a less precise throttle response. After fitting Stage 1 or Stage 2 software, this becomes an even more pronounced weak point.

Racingline silicone hoses use a multi-layer reinforced construction that resists expansion, heat and ageing. Smooth inner walls help provide more consistent airflow through the charge-air system hoses, which can improve throttle response.

Main benefits

• Maintain boost pressure without expanding, even on modified vehicles
• Reinforced silicone construction for long-term durability and heat resistance
• Smooth inner surface for more consistent airflow and sharper throttle response
• Direct replacement for the original hoses without modifications
• Available in various colours for a tidy engine bay

Compatibility

The supplier’s description explicitly lists the kit for the VW Polo VI GTI (AW) with the 2.0 TSI engine. The supplier’s compatibility table also lists the Audi A1 Sportback (GBA) with the 40 TFSI engine or CZPC/DKZC and DNND engines, so check compatibility with your vehicle before fitting.

Fitting notes

The hoses are direct replacements for the factory hoses and use the original hose clamps and mounting points. Fitting is straightforward for anyone experienced in working in the engine bay, although we still recommend using a service manual or having the kit fitted by a qualified mechanic. After fitting, check that all hose clamps are correctly positioned and tightened, as any loose connection can cause boost pressure leaks.

The VWR140010 boost hose kit eliminates a known weak point on the Polo GTI and is a suitable addition to a software upgrade or other improvements to the charge-air system.

Suitable for: Audi A1 II (GB), VW Polo VI (AW).
