This Samco Air box hose replaces the accordion piece that goes between the mass air flow sensor and the turbo inlet hose. These hoses are made of high quality reinforced silicone and will not collapse. By replacing this hose on your intake track it will allow for quicker turbo spool and will result in better air flow.
