The OPTIONAL Ram Air Kit allows you to get even more power gains by forcing cold, high velocity air into your air filter.

This Weapon R Secret Weapon intake is made to significantly increase the volume of air going into your motor. It is unlike any other short ram 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+ whp gain, depending on modifications.
  • An optional Ram Air Kit, which can be used to further increase horsepower gains. To use the Ram Air Kit, simply place one end of the tube on the top inlet of the air filter and the other end in an area that will have get a lot of cold outside air, like behind your front grill or fog light holes.
  • Easy to install and maintain because it's a short ram intake, but also offers the flexibility of getting cold air with the optional Ram Air Kit.
  • Features a high flow Secret Weapon performance air filter, made from special high-density foam.
  • Comes with installation hardware and instructions.
  • Award winning Dual Tube Velocity design.
  • Mandrel bent 6061 T6 aluminum intake tubing with polished finish.
  • Oil-free foam air filter.

Availability and Condition: Unless otherwise noted, this product is in brand new condition and usually in stock at one of our warehouses, or will ship directly from the manufacturer.
