Frequently Asked Questions
Is this a plug-and-play upgrade?
Mechanically, the TTE860 fits just like an RS4 K04 setup in terms of oil and water lines, but additional modifications to the Intake, exhaust, fuel and cooling systems are required.
Can I send in my own turbos?
Yes, this upgrade is possible provided you supply RS4 K04 OE turbochargers in good condition.
What additional upgrades are recommended?
larger injectors, upgraded fuel pumps, a free-flow exhaust, efficient intercoolers and professional ECU tuning are essential to safely realise the full potential.
