Racingline Polo Mk6 GTI (AW) Boost Hose Upgrade Kit

Racingline Polo Mk6 GTI (AW) Boost Hose Upgrade Kit – VWR140010

Replace the soft, failure-prone factory rubber boost hoses on your VW Polo Mk6 GTI (AW) 2.0 TSI with the Racingline Boost Hose Upgrade Kit. Made from reinforced motorsport-grade silicone, this direct-fit kit delivers a firmer throttle feel, more consistent boost pressure, and a tidier engine bay.

The original rubber hoses are known to balloon under load, especially on tuned cars. That expansion wastes boost, dulls throttle response, and over time can crack or split entirely. The Racingline kit solves this by holding its shape under pressure, keeping every bit of boost between the turbo and the engine where it belongs.

Why Upgrade the Boost Hoses?

On the Polo GTI’s 2.0 TSI engine, the factory hoses sit in a hot, high-pressure environment. As boost rises, the soft rubber flexes outward, creating a “spongy” feel through the throttle pedal. Once the car is tuned, that flex becomes a real weak point. Failed boost hoses are one of the more common issues owners face after fitting a Stage 1 or Stage 2 software upgrade.

Racingline’s silicone hoses use a multi-layer reinforced construction that resists expansion, heat and ageing. The smooth inner walls also help air flow more cleanly through the charge pipework, which can give a small but noticeable improvement in throttle response.

Key Benefits

• Holds boost pressure without ballooning, even on tuned cars
• Reinforced silicone construction for long-term durability and heat resistance
• Smoother inner surface for cleaner airflow and sharper throttle response
• Direct OEM replacement, no modifications required
• Available in a choice of colours for a clean, finished engine bay look

Fitment

This kit is designed specifically for the VW Polo Mk6 GTI (AW) fitted with the 2.0 TSI engine. Please use the site’s vehicle lookup or check the Vehicle Fitment tab to confirm compatibility with your exact model and year before ordering.

Installation Notes

The hoses are a direct swap for the factory items and use the original clamps and mounting points. Installation is straightforward for anyone comfortable working around the engine bay, though we always recommend referring to a workshop manual or having the work carried out by a qualified technician. Take care to check that all clamps are correctly seated and torqued after fitment, as any loose connection will result in a boost leak.

As an authorised UK dealer for Racingline Performance, we only supply genuine Racingline parts developed and tested through motorsport. The VWR140010 Boost Hose Kit is a sensible, well-priced upgrade that addresses a known weak point on the Polo GTI and pairs perfectly with software tuning or other charge system upgrades.
