Stillen 403235 Z-Tube Kit 03-08 Infiniti FX35 3.5L
The intake tract on the G35 and FX35 was not designed for maximum performance. Many enthusiasts have changed to the 350Z piping which is more aerodynamically efficient.
Our new STILLEN "Z-Tube" is a lower cost and better way of maximizing air flow in your G or FX. This is a rotomolded plastic part that has excellent insulation qualities. This helps to isolate incoming air from engine heat, the colder air produces more power. Use this with the stock airbox or for maximum gains add the Stillen intake
