The A.W.E. K04 kit for the 2002-2005 A4 consists of K04-15 turbo, A.W.E./GIAC
software, larger injectors, all gaskets, and Bosch spark plug set. This kit
utilizes the larger K04 015 turbo, with our specially designed GIAC software, to
good effect. This A.W.E. exclusive transforms your 1.8T into a lightning fast,
yet factory-reliable, rocket ship.

Dyno developed, track tested. Hundreds of hours of tuning and field usage has
resulted in a finely tweaked kit that delivers the goods! The cost per hp of
this kit is tough to beat, as is its ease of bolt-on install and factory
The key to the power improvements is the industry leading software from GIAC.
Many hours were spent studying the complex programming of the Motronic fuel
injection found on these vehicles, and determining how to integrate all the
essential maps for repeatable, predictable power improvements. Final tuning of
the fuel mixture, ignition timing advance, boost level, and monitoring of the
associated Exhaust Gas Temperatures was completed on the A.W.E. Mustang
load-type dyno, to ensure safe performance in the real world.
The software of each kit is tailored to the specific requirements of the
vehicles, so that a minimum of part replacements is needed to fit the larger K04
turbo. The stock intercooler and piping are retained, keeping the final price of
the kits and associated install labor affordable by all. Outward appearances are
totally stock OEM. Please note that a full flow exhaust system from the
catalytic converter back is required for use with this turbo.
Dyno results and driving impressions reveal an extremely broad powerband,
with usable torque as low as 2000 rpms, and hard pulling horsepower as high as
This much usable power makes for a very satisfying experience behind the
