For midrange power, 99/01 Cobra intake manifolds are pretty much the best... For all out high end hp, the fr500 intake is the better (it will make more peak hp), but lacks the low end tq... If your revving over 7k, I would go with the fr500, otherwise, just go with the 99/01 cobra intake manifold...
