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).

- Wow! This piece is an excellent addition to your aftermarket intake system. I have the AFE Pro Dry intake and this enhanced the sound and feel of the throttle response. For the price, you can't beat it. Easy install and the instructions were straight forward. Thanks again AFE!!
