Stillen Intake Z-Tube (w/Couplers) for Infiniti G35 Coupe / G35 Sedan / FX35 2003-2008

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.


Features & Benefits

  • Roto-Molded Z Tube: Durable construction with connections for all factory breather tubes.
  • Performance Gains: Increases throttle response and adds up to 11 HP (Sedan) or 5 HP (Coupe).
  • Improved Airflow: Eliminates factory baffling for greater flow efficiency and sporty induction sound.
  • Silicone Couplers: Prevent tearing and ensure long-term durability.
  • P0171 Code Solution: Permanently resolves lean condition caused by factory coupler failure.
  • Limited Lifetime Warranty: Backed by STILLEN's commitment to quality.

Note: Not for sale or use in California.

Enhance your Infiniti’s performance and reliability with the STILLEN Z Tube kit and silicone couplers.

In some cases, we may offer the ability to return the item to us for a lesser restocking fee and then keep the balance as a store credit. To return an item, it must be in brand new condition with original packaging.

                                                                                                                  We cannot accept a return on special ordered or custom items.

These items generally require a deposit or paid in full. Once this deposit amount is notified to the customer and they agree to order the special order item, the deposit becomes non-refundable. These special order items cannot be returned or resold. Cancellations are not allowed on special order parts.

                                                                                                                  AutoTalent DOES NOT REFUND SHIPPING CHARGES.

When you place an order with us we pay credit card fees that are NOT returned back to us. We will absorb these fees if we do not have the item in stock OR if you agree to the original ETA and that ETA is NOT met. If you decide to cancel for any other reason you will not receive this 5% fee back
