Cold air is in, and STILLEN can supply your G35 coupe or sedan with plenty of it. Long known as the leaders in Nissan/Infiniti performance tuning, STILLEN has introduced a Cold Air Intake System for the popular G35 coupe and sedan. Due to the different states of tune of each model, the intake adds 11horsepower 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 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.
