You don't need any additional components here. Simply install and have fun! No Longlife oil. Better use our GTX Racing Oil 10W-60.
BAR-TEK® TIP!
We recommend to fill up with 102 octane fuel. This will give your engine more power because it knocks less! The turbocharger should not be too old. Engine in good condition. The basis must be in good condition. Check the red pressure hose on the turbocharger, it's often leaky because it can't remove the heat from the manifold. To reduce coking to a minimum and keep the engine clean, we recommend installing our oil catchtank kit with TÜV.

stage 2
increased efficiency:

320 Nm

To get the extra power on the road you need a sports clutch, because the original one can't transfer the power. For the conversion to K04-001 turbocharger you have to install a 3" downpipe and our upgrade air mass meter.
BAR-TEK® TIP!
We recommend that you buy the Level 3 kit right away. With the stage 2 kit, without modified injectors and upgrade manifold the performance gain is not quite as high compared to the chip tuning. This is because the injection times with the original nozzles are at the limit.

BAR-TEK® TIP!
With the tuning kit stage 3 you have the extended extension stage of the kit 2. Here you have 380 ccm injectors and an upgrade manifold as well as an optimized software! If you have already installed a downpipe, intake hose and an upgrade intercooler, you can continue to use it. With an Upgrade intercooler you also have the complete performance available in summer!

320 hp: That's an announcement! To drive this power, you have to replace your connecting rods with our kit of connecting rods and pistons. A sports clutch kit is required to get the 320 hp on the road. For the exhaust you should use a 76 mm exhaust system. Since the oil temperature remains in the healthy range, an oil cooler kit must be installed!
BAR-TEK® TIP!
A good chip tuning is required for this conversion. You can send your control unit to us or have your vehicle tuned directly in our four-wheel dyno. Another tip from us: If you have installed the small 280 mm brake system, this is no longer up to the high performance. You can convert it to a Brembo 4-piston brake or to the 320 mm brake from the Audi S3, for example.
