Overview

Z-Tube for Infiniti G35 and FX35

The factory intake tracts on the Infiniti G35 and FX35 were not designed for maximum performance. On the other hand, the 350Z, which shares its engine with these vehicles, is equipped with a much more efficient intake tube that breathes easier and cooler than its Infiniti counterparts. The OEM 350Z intake tract fits the G35 and FX35, as long as you're willing to pay the price for OEM parts. If you want more power for less money, the experts at STILLEN have got you covered with the STILLEN Z-Tube. It offers all the performance of the 350Z tube without the high OEM price tag.

Z-TUBE

Made of roto-molded plastic, the Z-TUBE intake tract offers excellent insulation properties, isolating inbound air from engine heat. The result: a colder intake charge and increased power. You can run the Z-TUBE with the stock airbox. For maximum gains, we recommend pairing it with the STILLEN Hi-Flow Intake, part #402835.

INTAKE

Due to the different states of factory tune of each stock 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 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, producing a noticeable power bump. The Intake System also lends a more aggressive tone to the G35 and FX35 when pressed, but remains unobtrusive at cruising speed.

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.

About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
