The UroTuning/GIAC K04 kit for the B6 Audi A4 1.8T consists of K04-15 turbo, GIAC software, all gaskets and hardware, Bosch Audi TT 380cc injectors and Green coolant temp sensor. This kit utilizes the larger K04-015 turbo, with our specially designed GIAC software, to good effect. This kit. 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 appearance.

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 a Mustang load-type dyno, to ensure safe performance in the real world.

Outward appearances on the kit are totally stock OEM. Please note that a full 2.5" Turbo back exhaust system is highly recommended for use with this turbo kit.

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.

NOTE: This kit is only supported for 2002-2005 Passat 1.8T ** Some cars may require a VR6/TT225 MAF housing.

*Optionally add USPS Express Air shipping for your ECU Flash (this does NOT include next day shipping of the turbo kit).
