now i have a full aem on mine but honestly people can say they get 5 or 25 whp from one but i dont claim any of that. sure it may add some but to me its not worth claiming extra power from one cause all intakes are pretty much the same. mandrel bent metal tubing. i will agree with WideBodyEK that the better the filter you have the better flow but as for adding power eh dont claim it till you dyno it.
