The IE K04 hardware kit comes with a modified genuine Borg Warner K04 and hardware for an easy installation. This easy bolt-in turbo kit increases power up to 391HP & 398TQ with supporting mods and tune (sold separately) while retaining factory-like comfort and reliability!
With correct software and bolt-ons this turbo will bump you up into the 330-390hp range on pump fuel. Typically you’ll want a downpipe, intake, intercooler, and software. 6 Speed manual cars will also need an upgraded performance clutch.
From the beginning, our engineers wanted to make this K04 a simple, quick installation, without adding a lot of extra parts and mess. So, our team actually machines the compressor covers of the Borg Warner K04 turbocharger and attaches an adapter plate to allow the diverter valve to fit exactly in it’s OE location for TSI engines. This makes the installation quick, neat, and with no fitment issues you might have with aftermarket Diverter relocation kits. No wiring is required as a consequence of this.
The K04 turbocharger is a great turbocharger for the Gen 2 TSI engine. It delivers 330-350 horsepower which is a good, reliable amount on the stock engine. It makes the car an absolute riot to drive without becoming a chore to own and operate.
This turbocharger is an OEM turbocharger from the MK6 Golf R. We then modify it to place the diverter valve in the OE location so the fitment is exactly like stock for an easy install.
Once installed, the K04 appears entirely OE except for your bolt ons such as cold air intakes. By keeping the diverter in it’s OE location there are no ugly diverter relocation kits running silicone hoses all over your bay.
This K04 has been modified to drop into the place of the factory turbocharger with minimal work. CLICK HERE to view or download the full installation guide.
This IE K04 turbocharger kit is a turbo hardware only upgrade kit, and requires additional hardware and software to complete the installation.
The upgraded turbo kit and additional hardware will require a software upgrade to the factory ECU. Click here to purchase an IE K04 Tune
When upgrading to a larger turbocharger it is important to make sure your intake can supply your turbo with plenty of flow. We highly recommend upgrading to a performance air intake such as the IE Cold Air Intake Kit for MK5 & MK6 TSI Engines. IE Part Number: IEINCC2
The increased size, flow, performance, and boost of the larger K04 turbocharger will dramaticially increase the charge air temperatures and quickly cause heat soak. Once your intercooler is heat soaked, you will quickly lose huge amounts of power as intake air temps rise. Keep your K04 kit performing at its peak with an IE Audi & VW MK5 & MK6 2.0T FDS High Performance Intercooler. IE Part Number: IETPCB1
The factory restrictive downpipe can not provide adequate support for the larger K04 turbocharger, upgrading to a aftermarket performance downpipe is required for optimal power output. IE recommends a 3" downpipe to match your new K04 kit.
It is also recommended to upgrade to a higher output spark plug to provide plenty of spark for the increased cylinder pressure. IE recommends a set of NGK BKR7EIX Iridium Spark Plugs.
