Description The first step in upgrading your Nissan 350Z’s performance is to replace the restrictive stock air box with a STILLEN High Flow Intake. INCREASED ENGINE EFFICIENCY Additional air flow increases the 350Z engine’s efficiency and power output by increasing the quantity of the air/fuel ratio. The STILLEN High Flow for 350Z consists of a K&N cone filter that incorporates a velocity stack which uses the venturi effect to accelerate air intake speed. BEST DOLLAR-PER-HORSEPOWER INVESTMENT Power and throttle response will improve throughout the entire RPM range. Your best dollar-per-horsepower investment by far! Most people find the authoritative note of the High Flow intake pleasing, but note that increased noise levels will result.
