  • 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.

Every Secret Weapon Air Intake System comes with everything necessary for installation including comprehensive instructions.

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.

Weapon-R® makes high quality performance parts, at affordable prices, for sport compact cars. All products are carefully designed using the latest computer simulation and modeling techniques, followed by extensive dyno testing. Finally, all parts are rigorously street and race tested to make sure they’ll perform flawlessly in your car. Weapon-R draws on over a decade’s experience, involvement in various forms of motor sports, and their commitment to research and development, to bring you the highest quality and best value performance parts in the industry.

Better as a Short Ram.
I recently received my Neo-Ti secret weapon and installed it on my 2011 Scion Tc. Long story short, after testing it as both the short ram and having the plastic tubing installed, I noticed a loss in pressure and acceleration with the tubing. I am running it with tubing till I can get a vented hood, because it draws in too much hot air otherwise. After the hood, definitely going back to short ram. Massive difference over stock air box and Spectre air filter. Plus the Neo-Ti is gorgeous under the hood.:) Hope this review helped! :)

I guess your paying for the looks. This intake did not come with a heat shield like the Takeda & K&N do. It also doesn't come with a support bracket like the Injen. You really gotta hope the couplers will withstand time and the elements, cause that's the only thing holding this intake together and acting as the support for it at the same time. However, it does sound better than my Injen short ram I had on my '06 Mazda6.

Weapon-R 304-125-401B - Neo-Ti Finish
Installed on a 2004 Infiniti FX35. Everything worked out but the back air hose on the OEM intake tube points straight back and the one on the Weapon-R faces straight down, which I thought was pretty odd. It took some extra attention and modification to hook up if you wish to use the OEM air hose. You have to modify your own mounting bracket and find a mounting point. Not a big deal, but every other CAI I've put on in the past actually had "detailed" instructions. Overall a nice intake.

Awesome Prada Looks and Sounds Great!
I just recently purchased this new cold air intake for my 2006 Mitsubishi Eclipse. After installation, I noticed an improvement in performance and horsepower, and not to mention the overall sound of the engine! I would highly recommend this product to anyone who has a fourth generation Eclipse.

G35 2004
The product is awesome! The sound: incredible, the power: u feel it once u step on that gas. The other day I stop in a red light next to another G35 his was a 2006. He started to make noise and when I step on my gas pedal he started laughing and ask what u have in there? Lol the only problem is that your car is going to consume more gas, u are going to see the difference but of course u will gain more power to that engine. And the installation is easy they say 90 min, mine took me less than an hour. Great product. I recommended if u are in the racing industry.
