Eventuri's answer was to completely re-engineer the inlet track from the front grille all the way to the turbo inlet pipe with a fully sealed, highly efficient system rather than accepting that trade-off.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe restrictive stock airbox and flexible plastic inlet pipe are replaced entirely with a one-piece Venturi filter housing and solid duct system, eliminating the convoluted rubber section that disrupts airflow on the factory setup.
