Silicone Hoses

The 2.7T platform is far from dead, tuners continually making more and more power with them.åÊ Stock fitment components are becoming less and less viable as power levels sky rocket past the typical 500HP Stage 3 power level.åÊ Inlet flow to the turbos is an issue with the stock y-pipe and inlets being approx 2" for 2 feet plus.

Using big bore 034Motorsport silicone hoses allows a full 2.5" diameter transitioning to the lower RS4 inlet pipe, ensuring ample flow for high power levels.åÊ Those building custom inlets can run a 2.5" all the way into the turbo and trim the transition off the 034 big bore hose.

The inlet of the hose is sized for the RS4 y-pipe so its a perfect compliment to our high flow carbon y-pipe, or can be spaced down to use with a stock S4 y-pipe.åÊ Provisions for factory location bypass valves.

High temp silicone hose with wire reinforcement to prevent collapse under any conditions.

Awesome GTI Delivery Information

Do we ship abroad ?

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

There are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Yugoslavia, Romania, Croatia, Hungary, Slovakia, Slovenia, Russia, Nigeria, Macedonia, Singapore, Bulgaria, Ukraine, Lebanon and Lithuania.

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 UKMail 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.
