Product Description

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.

I wanted a practical way to gain some horsepower from a cold air kit that fits in the stock location under the hood. Not to loud except on hard acceleration. Good bang for the buck.

Have not Dyno'ed yet to tell the difference between stock one.
But the throttle sound is noticable deeper when pushing hard and big volume of air is sucked.
Please, don't be surprised when you receive only tube and installation manual, because it is what you have ordered.
Personally I like this product, with it was cheaper.

Don't buy through stillen, they tries to charge me twice and say they sent me two even though I only ordered one and received one. Otherwise product itself is awesome. Just don't recommend going through stillen

Exactly what I was looking for in my cars set up, as my old intake tube was metal and was sucking in nothing but hot air. This thing stays cool and is easy to install. I'd recommend it!
