Did you get that 100 miles in yet? Would you say if there was one thing you did to your truck for performance then this would be "It"?
That is to say are they trully worth spending the cash, or should all my saveings go into another performace upgrade? I need power but my wife will kill me if I go blowing more cash on parts that don't make much difference to the performance.
I say speed is money, hony
