yes have heard good things again about that but it needs setting up right , i think the induction system is one of the hardest things to get right as alot are open systems and you get alot of heat soak off the engine , you could maybe try the fiesta st180 itg filter head with custom pipe work to get it down behind the head light so its out of the way , it works very well , most of my mods were more replace with stonger parts before i have a massive bill on my hands , i would defo do the billet lever on the inlet.
next for me would be cams with vvt delete or head work with cams after that itd throttle bodies or turbo and turbo would be cheaper and easier
