Silicone Hoses

Upgrade the turbo outlet hose / throttle body inlet hose set on your Audi C7 S6/S7/RS7 or D4 A8/S8 4.0T with our ECS Tuning in-house designed and engineered 4-ply Silicone Turbo Outlet Hose Set. The factory rubber hoses on your 4.0T are known to heat harden and crack over time, causing loss of boost pressure and vacuum leaks. Our ECS Silicone Hose Set was engineered to fit directly in place of the factory hoses while resisting oil, fuel and ozone degradation and are tested up to continuous operating temperatures of 250° Fahrenheit while supporting up to 45psi of pressure.



  • In-house designed and engineered using FARO ARM laser scanning technology and SolidWorks 3D CAD modeling for precision fitment 

  • Manufactured from 4-ply fiberglass reinforced gloss black silicone for durability and great looks 

  • Stainless steel, smooth band, German style hose clamps are included for a secure connection 
  • ECS Tuning logo positioned front and center when the hood is open, with the engine cover removed

Awesome GTI Delivery Information


For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.


Not everything on our website is in stock, if you need a part desperately please contact us first to confirm availability before placing your order
