The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with Helix only designs.

- 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!!
