Actually, intake and exhaust properly tuned on the new Duratec Focus will net you over 12 horsepower on the dyno, not a bad gain for a 140hp motor. So it's not as "bling" on those I know for sure. On top of that, if you get some of the other parts like intake manifold, cams, header, you will see a huge gain. The thing about the small mods is they work to make the big mods way more efficient. It's a good start.
