The new WagnerTuning Air-Intake-System is a direct replacement for the stock system and removes all OEM bottlenecks. The flow-optimized carbon airbox cover and the Ã˜89mm carbon pipe ensure the best possible airflow characteristics without unnecessarily blocking or swirling. Through its use the airmass flow rate increases by 32% and the response time and the power output of the engine will be improved. In addition, the new WagnerTuning Air-Intake-System is a real eye-catcher inside the engine bay, because of the optical appearance as well as high quality finish.
The kit comes with:
1 carbon airbox cover
1 Ã˜89mm carbon pipe
2 silicone hoses (black)
1 mounting material
1 installation instruction
