The OEM hose is made from soft, unreinforced rubber, which implodes when the airflow demands are slightly higher than stock. The EVP V-FLOW reinforced airbox intake hose is made from high-strength silicone with internal steel wire reinforcement, which guarantees the hose cannot implode.
Other EVP reinforced silicone products to replace the inferior OEM parts are also part of a complete kit and are available separately.
