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.
