This Weapon R Secret Weapon intake is made to significantly increase the volume of air going into your motor. It is unlike any other intake on the market. The concept is to create two different air velocity profiles, one traveling at a higher speed than the other. This technology increases air volume and air speed, which naturally feeds your engine 3x more air than conventional air intake systems. The intake pipe is bent out of high quality 6061 T6 aluminum on Weapon R's automated CNC mandrel bender and then polished to a high show quality finish.

The Secret Weapon air filter (included) features a tuned velocity stack to increase air speed and decrease air turbulence. The filter material is made from open pore high-density foam, and does a great job of blocking dust/dirt particles without sacrificing performance.

Key Features:

• 6-14+ horsepower gain, depending on modifications.
• Easy to install and maintain.
• Features a high-flow Secret Weapon performance air filter, made from special high-density foam that is oil-free. NEW: filter now comes in Stealth Black!
• Comes with installation hardware and instructions.
• Award winning Dual Tube Velocity design.
• Mandrel bent 6061 T6 aluminum intake tubing with polished finish.
