CNC Machined out of the Highest quality lightweight aluminum, our unique design will optimize your throttle body passage with almost 1700cfms of airflow, that is an improved gain of over 600 cfm! By machining out the upper and lower intake walls, LFPs new Big Mouth optimizes airflow, outperforming the competition. Throttle body is anodized to protect from oxidation and a GREAT LOOK! This is the perfect addition to your new Whipple or Kenne Bell Supercharger. In addition to the horsepower gain, you will notice a much improved throttle response.
