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.

  • 034 Motorsports Manifold

    Posted by Jack on 4th Nov 2023

    Excellent so far - Previous review states faster boost times, happy to confirm this on my car.

    1.8t, standard internals but fitted with AET rebuilt KO4-001 for ease of fit, bolts up to this manifold perfectly. Mk1 Audi TT, originally 180.

    Tricky to fit to the car with engine in situ, had to make myself an open ended swan neck spanner (AwesomeGTI customer services were very nice when called about this)
    Not impossible but at least 4/5 spanners if it were in a Haynes manual.

    Manifold itself is much thicker, which while making fitment more difficult, does make the manifold more durable and less prone to cracking as the two replacement manifolds I had ready to fit had done.

    Engine bay temps do seem hotter but this is normal for any tuned 1.8t.

    Re power, impossible for me to say definite improvement as fitted alongside a larger turbo & injectors incl map.

    Garage did remark on how much faster the turbo spooled compared to other 1.8t’s

    Overall, good performance, difficult to justify price but if you’re after a well performing piece of hardware, it’s hard to knock this.

    Pleasantly pleased.

  • Good upgrade

    Boosts so much quicker but this manifold dose get real hot and engine bay temps are high over standard manifold temps
