Z-Tube for Infiniti G35 and FX35
The factory intake tract on the Infiniti 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 as we all know can be very expensive, however. The STILLEN Z-Tube offers all the performance of the 350Z tube without the high OEM price tag.
Made of roto-molded 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.
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 that has reviewed these has raved about the G35's performance characteristics; and the STILLEN Hi-Flow Intake System is the perfect way to add an edge to yours.

Jonathon Murrillby Jonathon MurrillInstalled on my 05 g35 coupe. Super easy to install and the difference is definitely noticeable. Very impressed. Tasteful yet mean. Two thumbs up!4/9/2014
Wesley Jonesby Wesley JonesFirst of all, the great people at Stillen got my Hi-Flow Intake and Z-Tube to me super fast. The intake itself is amazing so far. My FX sounds more aggressive and I can definitely feel additional power. The only issue is that I had to go and buy 4 M6-1.0 x 20mm screws because the stock and provided screws did not work well. Overall, amazing product that is easy to install and has very noticeable gains in power and in sound.
Sam Rauseoby Sam RauseoInstalled the Hi-flow intake w/ Z tube on my '03 G35 coupe. Had it on about a week and absolutely love it. Looks great, throttle response is quicker and it sounds so mean! Great intake.
