The Scion xB Secret Weapon cold air intake was designed, to increase air intake volume to the engine. The concept is to create two different air velocity profiles, one traveling at higher speeds than the other. This technology increases air volume and speed to the engine, which naturally feeds the engine 3x more air than the conventional air intake system. The intake pipe is bent out of high quality 6061 Aluminum on our Automated CNC mandrel bender. Polished to a high show quality finish. The SW1 Air filter features a tuned velocity stack to increase velocity and decrease turbulence. Only Comes In Polished. 1 Million Mile Limited Warranty.

In other words, the same great secret weapon technology has found its way into the form of a cold air intake system. The CAI can achieve lower air temperatures, and the extended length allows for Weapon R's dual chamber technology to create even more suck for your buck. Aside from the performance, you are also getting a great looking polished finish. When you put those things together and then add the superior manufacture and assembly process, top notch materials, and the million mile warranty, you cannot go wrong. This is simply the best intake available on the market.
