This intake kit replaces the complete air filter housing, including the original intake trumpet. When removing the original air filter housing, you will already notice that the original intake trumpet routing is rather restrictive. The HFI Airbox system offered here is made from carbon fibre and features a special Pipercross DRY sports air filter developed specifically for this system. It is not oiled and therefore cannot damage the air mass meter. Pipercross filter airflow: 503,1cfm
