The airbox to throttle body intake boot is made out of thin soft rubber with no reinforcement to stop itself from collapsing in on its self when warm and under a heavy load. We have fixed this flaw with a extremely heavy duty 8.5mm thick 5Ply silicone tube that is not only stronger but also oversized. When designing this we removed the factory restrictive to airflow imperfections & smoothed the transitions and clearance points to the max providing the absolute most intake air flow and velocity possible. Each tube includes stainless Silicone Safe T-Bolt clamps and factory crankcase ventilation port.
