Racingline Silicone Boost Hose Kit for MQB EVO EA888.4 – VWR140006

Racingline Silicone Boost Hose Kit for MQB EVO EA888.4 – VWR140006

The Racingline Silicone Boost Hose Kit is a direct replacement for the soft rubber charge pipes fitted to the latest Generation 4 2.0 TSI EA888.4 engines. The factory hoses are designed to cope with standard boost levels, but on tuned cars running higher pressures and temperatures, they can flex, distort and even collapse under load. This three-piece silicone kit solves that problem with reinforced, smooth-flowing replacements built to handle far more than the turbo can throw at them.

As an authorised UK Racingline dealer, we supply this kit as an essential upgrade for anyone running a remap or planning further tuning on their EA888.4 powered Volkswagen, Audi, SEAT or Cupra.

What the kit does

The kit replaces the three original charge pipes (the hoses that carry pressurised air between the turbo and the intercooler, and onward to the engine). Swapping the standard rubber for Racingline’s reinforced silicone gives you a stiffer, more consistent airflow path that does not balloon, soften or collapse under boost.

Internally, the hoses use stepped joint transitions that port-match to the surrounding hardware. This creates a smoother, more laminar airflow path (air moving in even layers rather than tumbling around), reducing turbulence compared with non-stepped designs. The result is less restriction for the turbo to work against, helping it move a greater volume of air more efficiently.

Key features

• Three-piece direct OEM replacement kit, no modifications required
• Reinforced silicone construction rated well beyond the turbo’s output
• Internal steel wire helix in both intercooler hoses to prevent collapse under vacuum and high heat
• Stepped, port-matched internal joints for smoother airflow
• Pressure tested to withstand sustained high-boost and high-temperature use

Why the steel wire helix matters

The two intercooler boost hoses carry hot, pressurised air over longer runs where flex is most likely. Racingline buries a steel wire helix within the silicone wall, which keeps the hose perfectly round under all conditions. You still get the flexibility needed for fitment and engine movement, but without the wall distortion that robs power and consistency on tuned cars.

Who it suits

This is a particularly worthwhile upgrade for any remapped EA888.4 2.0 TSI running higher than standard boost. It fits popular MQB Evo platform cars using the Gen.4 EA888 engine, including a range of current Volkswagen, Audi, SEAT and Cupra models. Please use the vehicle lookup or check the Vehicle Fitment tab to confirm this kit is correct for your exact car.

Installation

Fitting is straightforward for anyone comfortable with basic spannerwork: remove the three factory hoses and fit the Racingline replacements in their place. No cutting, drilling or adapters are needed.

Racingline Performance develops its products in motorsport, the toughest testing environment there is, before refining them for road use. The Silicone Boost Hose Kit is a simple, effective hardware upgrade that addresses a known weak point on tuned EA888.4 engines and helps your turbo deliver its boost more cleanly and reliably.

Applications

Please note, customers are wholly responsible for checking fitment for their vehicle.
