STILLEN 403235 Z-Tube Without Intake - 03-07 G35 Coupe / 03-06 G35 Sedan / 03-08 FX35

The intake tract on the G35 and FX35 was not designed for maximum performance. The 350Z, which shares its engine with these vehicles, is equipped with a much more efficient intake tube that is interchangeable with the G35 and FX35. OEM parts are expensive, however. The STILLEN Z-Tube offers all the performance of the 350Z tube without the high OEM price tag.



Z-TUBE



Made of rotomolded plastic, this product has excellent insulation qualities. This helps to isolate incoming air from engine heat, resulting in a colder intake charge and increased power. Use this with the stock airbox or for maximum gains add the STILLEN Hi-Flow Intake, our part #402835.



INTAKE



Due to the different states of tune of each model, the intake (independent of the Z-Tube) adds 11 horsepower at 6,100 RPM to the G35 Sedan and 5 ponies at 5,700 RPM to the Coupe. Comprised of a high-quality polyurethane intake port, washable and reusable cotton filter element, and STILLEN's signature Aluminum Venturi Ring, the Intake draws air from outside the engine bay.



The Venturi ring acts as a velocity stack, speeding up and directing the airflow into the intake chambers, making more useable and noticeable power.



The Intake System also lends a more aggressive tone to the G35 and FX35 when pressed, but remains unobtrusive at idle. Every magazine has been impressed with the G35's performance characteristics; and the STILLEN Hi-Flow Intake System is the perfect way to add an edge to yours.



Z-TUBE / INTAKE COMBO



The Z-Tube / Intake Combo package is the affordable way to upgrade the entire intake tract, combining the Z-Tube (Part #402834) and Hi-Flow Intake (Part #402835) in one convenient part number.
