I have one, and i must say it was worth the money, better throttle response, gained a few ponies, makes my auto feel more alive. I went with the CFM 67 mm throttle body.
Everyone that I have encountered who owns a Focus w/an auto tranny love them, most people with a manual say its hard to get use to, so hard they take them off and return to stock. They say you pretty much have to relearn how to drive ur stick.
So if you have an auto, ull love it. If you gotta manual you might love and hate it!
^^^X2 I have an atx and also felt the difference. My gf gave me the cosworth but honestly I wouldn't pay 400+ bucks for a throttle body (not worth all that money imo). You will feel better throttle response, "faster" acceleration, just as if the car is more awake if you have an atx. If you have a manual then I don't know lol.
ya i have a bbk. throttle response is better, not that hard to get used to. it makes the car a little more fun to drive
as for being worth the money...hmmmm, personally yea, i hated the lack of response the car gave me stock. if u get other bolt ons as well theyll work together, and then its definately worth it
Really the upgraded throttle body doesn't give you any more HP without having FI. However it does give some nice throttle response. I have the CFM 67mm with AEM CAI and 2 1/4" trubendz exhaust and i'm pushing 134 HP and 136 TQ at the front wheels in my NON-pzev.
I have a ported stock throttle body on my mtx and the throttle response still feels strange. I just installed it 3 days ago. I'm still getting used to it and with it raining today I keep getting a bit of wheel spin every time I take off from a stop sign/light. It does feel better while actually moving though as long as I don't have to shift. When shifting I tend to over rev a bit. Hopefully I can get used to it pretty soon.
