K04 F.A.Q.s

What there is to know about the K04 Turbo swap!

When tuning your car, you can only push your stock OEM parts so far. Running a Stage 2 tune is the furthest that many companies recommend you go on your stock K03 turbo. For those who want more, there is the K04 turbo kit. This turbo kit allows you to run a Stage 2+ and Stage 3 tune in your Audi or Volkswagen. With the K04 turbo kit and the Stage 2+ tune, you will bump up your car from its stock 200 Wheel Torque/194 Wheel Horsepower to 340 Wheel Torque/312 Wheel Horsepower.

The K04 Turbo Kit is made by several companies. Those companies are:

K04 Brands

When upgrading to the K04 turbo kit, there are some things that are required and some that are recommended that be on your car if you want to go K04:

  • Intake System – many companies will require that you have their brand intake system on your car if you are buying their K04 kit
  • Exhaust system – it is required that you have an aftermarket downpipe but a cat back exhaust is not
  • Upgraded Intercooler or Front Mount Intercooler – look to what brand K04 turbo kit you buy, some say this is recommended and some say it is required
  • Transmission – it is recommended that you upgrade the clutch to withstand the high levels of torque that the car will be putting out, as well as help transfer power to the ground
  • Spark plugs – it is recommended that you run spark plugs that are gapped to 0.024″ ±0.002″ or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km
  • Fuel Pump – it is required that you upgrade to a high pressure fuel pump
  • Fuel injectors – upgraded fuel injectors is required by some brands but not all
