STILLEN provides a permanent solution to the common issue of cracked intake piping and P0171 lean check engine light codes in Infiniti G35 and FX35 vehicles. Designed to replace the flawed factory intake couplers, the STILLEN Z Tube kit features high-quality silicone couplers and a roto-molded intake tube. This upgrade improves airflow efficiency, enhances throttle response, and eliminates the risk of unmetered air affecting engine performance. Originally inspired by the Nissan 350Z’s sporty intake design, this kit offers a blend of reliability and performance.
