Racingline Silicone Boost Hose Kit for MQB EA888 Gen.3

Racingline Silicone Boost Hose Kit for MQB EA888 Gen.3 – VWR140004

The Racingline Silicone Boost Hose Kit is a direct replacement for the factory rubber boost hoses on MQB platform vehicles running the EA888 Gen.3 2.0 TSI engine. Designed to handle higher boost pressures with no flex or expansion, this kit delivers firmer throttle response and far greater long-term reliability than the original rubber pipework.

Factory rubber boost hoses are a known weak point on tuned EA888 engines. Under sustained boost they can balloon, soften, split, or pop off completely, leading to sudden boost loss and a noticeably sluggish drive. Replacing them with reinforced silicone is one of the most worthwhile reliability upgrades you can make to a Stage 1 or Stage 2 car.

What the Kit Does

Each hose is made from multi-layer, motorsport-grade silicone with internal reinforcement to stop expansion under pressure. That means all the boost your turbo produces is sent straight to the engine, rather than being absorbed by flexing rubber. The smooth inner bore also helps air flow more cleanly through the charge pipe system, reducing turbulence between the turbo, intercooler and throttle body.

On a standard car you’ll notice a sharper, more immediate throttle feel. On a tuned car, the benefit is even greater – the original hoses are simply not built to cope with the pressures that come with remapped power levels.

Key Features

• Multi-layer reinforced silicone construction built to motorsport standards
• Resists expansion and ballooning under high boost
• Smooth internal bore for cleaner, less turbulent airflow
• Complete kit – includes all boost hoses needed for full replacement
• Available in a range of colours to tidy up the engine bay
• Designed to pair perfectly with the Racingline MQB Intercooler

Fitment

This kit is designed for popular VW Group MQB platform vehicles running the EA888 Gen.3 2.0 TSI engine, including models from Volkswagen, Audi, SEAT, Cupra and Škoda. Because there are several variations across the MQB range, please use the vehicle lookup tool or check the Vehicle Fitment tab to confirm this kit is correct for your exact car before ordering.

Why Upgrade the Boost Hoses?

Boost hoses are often overlooked, but they are critical to how the entire turbo system performs. A weak hose can undo the benefits of an upgraded intercooler, intake or remap. Fitting a silicone boost hose kit is a sensible step for anyone tuning their EA888 engine, and a worthwhile preventative upgrade on standard cars that are seeing high mileage or original rubber pipework showing signs of age.

Note: Where possible, we recommend fitting new constant-tension clamps during installation to ensure a secure, long-lasting seal on every joint.
