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