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.

More Than Expected
First of all, this kit includes the ram air intake, too. It is polished to a mirror shine, but shows some manufacturing marks. It's pretty, but makes you want more. After installation, pedal felt lighter, and I found I was speeding, by accident. I improved the fuel economy by 11.22 percent. Installation was a little more complicated than expected- not due to this product, but rather due to strange engineering choices by Honda. The iacv pipe interferes with a clean installation- had to cut off old tubes, instead of removing them- you can use the excess tubing this kit comes with or aftermarket tubing (which I did) to make things clean. Also, the thermostat sensor fit very loosely. A little creativity with electrical tape and a razor fixed that issue easily. Overall, I'm very happy with this product, albeit a little annoyed by installation issues.

Looks good and easy to install. Only thing I do not like are the silicone hoses. Seems like I can never get the hose clamps tight enough. Seems like I need hoses that are a little stiffer. I plan on buying some more to replace the ones that came with the intake.

The installation would be easier but i had a throttle body spacer which pushed the pipe right next to my battery so i had to modify the position of my battery, other than that i have no complaints. The induction noise became really aggressive above 3k, which is really nice.

2004 Hyundai Tiburon
Where to start with this product... The installation of this intake was very easy to figure out. Only reason I rated it a 4/5 was due to the very tight fit into my 2004 Tiburon. Everything else about this intake is easily 5/5, no doubt! The product looks amazing and sounds amazing. I easily notice a horsepower increase! All my friends love the sound and look of my Dragon intake. If you are considering to buy this product or not and skeptical on your decision, let me be first to tell you that it is totally worth your money. Do not buy any other product! This company does an awesome job taking care of their products and customers.
