- Select whether you are using an S4 Airbox, RS4 Airbox, or Cold Air Intake below. Select your engine code (APB or BEL) below. The BEL engine will require aftermarket or stock downpipes from an APB engine.
- If your vehicle is an early 2000 model with a Bosch MAF Sensor, it will need to be converted to the later Hitachi MAF Sensor. You can use our Plug in 2.7T Bosch to Hitachi MAF Sensor Conversion Kit for this.
- You must send us your ECU in order for us to perform the 034Motorsport Stage 3 ECU Upgrade. If you would like us to send you a tuned ECU before you send in yours, then we will charge you a $300 core charge, which will be refunded once we receive your stock ECU.
