Increased Engine Efficiency
Additional air flow increases the Altima engine's efficiency and power output by increasing the quantity of the air/fuel ratio. The STILLEN air intake for Altima consists of a K&N cone filter that incorporates a velocity stack which uses the venturi effect to accelerate air intake speed. Power and throttle response will improve throughout the entire RPM range. The note of the High Flow intake is very pleasing, but note that increased noise levels will result.
