Nissan 350Z 2003-2006, Secret Weapon Air Intake System by Weapon-R®. The Secret Weapon Air Intake System uses patented technology to feed the engine 3 times as much air as other systems. As a result, engine performance is increased more than with any other system available.
Patented technology increases airflow 3 times more than conventional systems.
Each system is tuned to maximize engine performance output.
Every system includes the revolutionary Secret Weapon Air Filter.
Dyno-tuned air intake pipe constructed of CNC mandrel-bent 6061 aluminum for smooth airflow.
Comes complete with all necessary mounting hardware and comprehensive installation instructions.
All Weapon-R foam air filters are backed by the Weapon-R Million Mile warranty.
To create an air intake system with the highest airflow possible, the engineers at Weapon-R experimented with basic laws of physics. They found that by creating two different air velocity profiles in the intake tube, both traveling at different speeds, it increased overall air speed and volume to the engine, naturally feeding the engine 3 times more air than a conventional air intake system. To implement this patented technology, Weapon-R CNC mandrel-bends 6061 aluminum to the desired shape, and then polishes it to a show quality finish. The intake tube is then matched with Weapon-R?s Secret Weapon air filter. The Secret Weapon air filter features a tuned velocity stack to increase velocity and decrease turbulence. The dramatic increase in airflow results in a greater increase in engine performance than would be possible with any other air intake system.
Weapon-R® Ram Air Kit II turns your air intake system into a Ram Air Intake. The Ram Air Intake brings cooler air to your intake system. Cold air is denser and contains more oxygen and cooler engine air inlet temperatures result in more power. Furthermore, the Ram Air tube is made from a high temperature fire resistant plastic, to resist heat soak which robs horsepower from your engine. The Ram Air Kit is easy to install. Just connect the hose to the top of the air filter, mount the velocity stack in the lower part of the grille and attach the hose.
