The factory Infiniti bellows couplers are prone to premature failure due to engine movement, which can allow unmetered air into the intake system. This often triggers the P0171 lean code, reducing performance and drivability. The STILLEN High-Performance Silicone Couplers replace this weak point, ensuring reliable airflow, preventing lean codes, and maintaining consistent performance for your STILLEN Z-Tube intake system.
