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.
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.
