402834 / 402834 - Application Notes



Our new intake / Z tube package is the affordable way to upgrade the intake on the G35 2 or 4 door models and FX35. The highly efficient Z tube (see part# 403235 for further details) is combined with our best selling Cold Air Intake System (see part# 402835 for complete details) for the popular G35 coupe and sedan and FX35. Due to the different states of tune of each model, the intake (independant 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 Cold Air Intake System is the perfect way to add an edge to yours.
