Q:Hello my name is Daniel and I am trying to gain extra horsepower everywhere I can for my 2007 Lincoln Navigator L, 5.4L V8. Last week I just had Borla straight pipe exhaust installed. I gained about 15 hp & the truck sound great, 150% Improved. Now I am looking into the K&N 57-2575 high performance intake system to possibly gain roughly 25 more horses.... What is the hp to torque ratio for this system? Show Less
