This intake manifold eliminates the secondary butterfly system of the stock manifold. By doing this we eliminates the dip in horsepower in the midrange and provide big horsepower gains all the way to redline.This is the perfect intake manifold for direct port nitrous and forced induction systems.You can see form the dyno chart that there is as much as 30 extra horsepower near redline on a stock engine with our intake manifold! Turbo cars will realize much greater horsepower gains!
