Im looking to gain some hp out of my 2010 ford focus se. I was thinking a cold air intake, exhaust and headers and performance chip? Im not a big car guy so idk much about brands and what does what so i came here. What would you guys suggest as far as brands and even other items i didnt mention. And what kind of hp gains would i see? i only have 1500 so i cant go stupid crazy and get a turbo kit. Any help would be awesome!
