The Serrated/Helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber resulting in increased horsepower, torque and improved throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other helix only designs. (US PAT 07055513)

- throttle body spacer is a must
- I"ve had this installed for over 3 years on my Infiniti QX80. Combined with the Momentum GT cold air intake, horsepower is improved but the best part has been the IMPROVED MPG! This truck is a big girl and every mpg improved is a win. The build quality combined with the detailed instructions won me over as an AFE customer. I now install AFE products on all of my builds.
