I recently installed the BBK 66mm unit and regardless of the debate in power gains I would recommend this to everyone. Throttle response is so much better at all rpms, the car just feels more willing to go. Not to mention that the stock throttle body is so poorly designed the inside flap is thick and curved Restricting airflow.

If you don't want to pay 250 for a CFM goto eBay and buy the 66mm SVT focus throttle body from BBK it is posted as a buy it now for 250 or there is an option to make an offer. Both sellers that have the make an offer option accepted offers for 200.

Thanks for the responses guys and thank you to whomever it was that merged the threads couldnt delete the one I didnt mean to post. I have a friend that is looking into just half shafting the stock throttle body or else some other modification may be in order I will update everyone when I am done with it. I know that there is really no HP gain with a larger one and am just looking for something with a little bit better throttle response for the FWD Rallys I have been competing in.

When you push on the gas pedal you get what feels like a better response. Less delay when accelerating. I've had mine on for years and def recommend it. It's kinda one of those mods that when you install, your like, it should have came like this from the factory.

Try throwing a 1.5lbs shift knob on top of that. You'll never go back to the stock shift lever ever.
