Increase engine performance with the STILLEN air intake for Nissan Altima L33. The Hi Flow intake features the most optimal horsepower and torque gains. This STILLEN Nissan Altima air intake has a polished finish. This L33 Altima intake provides a better air flow to the engine with the smooth surface tubing construction.


The first step in upgrading your 5th gen Nissan Altima's performance is to replace the restrictive stock air box with a STILLEN High Flow Intake.


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 High Quality STILLEN Washable Oiled 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.


Extra Performance and Sound-Pair up the short ram air intake with a STILLEN Stainless Steel Axle-Back Exhaust System for 2016 + Nissan Altima L33


CARB Exempt & Nissan Altima Intakes


Most STILLEN High Flow Intakes are CARB Exempt, while others are currently CARB Pending, and may not be 50 state legal until Exempt. Clean your filter regularly for best results.
