RacingLine 2.0 TSI Boost Hose Kit | Golf R, GTI and Audi S3

The RacingLine Boost Hose Kit for 2.0 TSI MQB smooths airflow and optimises routing - for more effective performance in high boost, high temperature use. 

What Do They Do?  

Welcome to the ultimate Boost Hose Kit for 2.0 & 1.8TSI MQB vehicles. The RacingLine Boost Hose package replaces the original rubber charge pipes with beautiful smooth-flowing silicone replacements, uniquely reinforced with internal wiring for guaranteed stiffness under the demands of high heat and boost levels.  

• By minimising restrictions, the smoother airflow and optimised routing ensures the turbo meets less resistance and can thus perform more effectively - moving a larger volume of air and minimising turbulence 
• Direct OEM replacement: simply remove the old weak, flexible rubber hoses and replace them with our five-piece kit
• Pressure tested far beyond the turbo’s capabilities, the system maintains performance under extreme temperature and high-boost conditions 
• Stepped internal joint transitions give a port-matched laminar airflow path, greatly reducing turbulence versus non-stepped designs

Five Piece Kit: 

The RacingLine Boost Hose Kit is probably the only one on the market which comes with five hoses included - however you'll only need to fit four of them. 

The choice of which Turbo Outlet Pipe (4a & 4b) depends on whether your car is pre- or post-2017. It's really easy to choose which to use, as it's either long or short depending on what OEM pipe you remove meaning that (unlike other kits) you can't really get this wrong!

Precision Engineered For Perfect Performance: 

• Constructed from internally-wired reinforced high quality silicone, guaranteeing great rigidity to prevent deformation under high boost or heat loads
• Fluorosilicone interior surface resists oil and gasoline permeation providing extra protection against deterioration 
• Stainless steel Mikalor-brand clamps reduce the risk of boost leaks with increased connection strength and decreased hose slippage
• Multi-ply silicone outer construction is hand-wound for performance under extreme conditions, ensuring both heat and burst resistance
