AVO Silicone Air Intake Hoses BRZ FR-S T86 Legacy GT Engine (10-up) All spigots on the PERRINhis wire reinforced 5 ply Silicone Inlet for the Subaru BRZ and Scion FR S is much larger than stock, especially at the bend. The interior of the OEM inlet is 70mm (and gets reduced further at the bend), while the AVO measures 76mm throughout! This translates to over 10% better airflow, especially as it removes the accordian section. The wire reinforcement ensures it will not collapse, even under the harshest conditions!
