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.

It is black anodized for a durable long-lasting finish. This premium wrapped coupling is constructed of high temperature silicone which meets or exceeds SAEJ20 Standards.
