The AWE Tuning K04 Kit for the 1.8L Turbo set a standard for K04 upgrades. Dyno developed, track tested, and hundreds of hours of tuning and field usage brings us to the finest example of B5 daily driving power delivery. Easy, bolt on install, factory appearance, reliability and AWE Tuning customer service. All part of the package.

What's in this baby?

The AWE Tuning K04 kit for your 1.8T consists of the Borg Warner K04 turbo, AWE Tuning/G.I.A.C. software, a performance Fuel Pressure Regulator, all gaskets, and hardware required for installation and a Bosch spark plug set. This kit utilizes the larger K04 015 turbo, with our specially designed G.I.A.C. software, to good effect. This AWE Tuning exclusive transforms your 1.8T into a lightning fast, yet factory-reliable, rocket ship.

Note: You're going to need a high performance exhaust, and it's recommended that you upgrade to a high performance Front Mounted Intercooler and if Tiptronic is your transmission of choice, you may also want to update your transmission software with a Tip Chip.

The story behind it all

The key to the power improvements is the combination of heavily engineered AWE Tuning hardware coupled with industry leading software from G.I.A.C.  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 were completed on the AWE Mustang load-type dyno, to ensure safe, consistent and meaningful 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 can be retained, piping and fuel injectors are retained, keeping the final price of the kits and associated install labor affordable by all. Outward appearances are totally stock OEM. Again, 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 6700 rpms.
