Hey evevrybody, sorry if this is a dum question but i would like to know what would be the difference between getting a 70mm or a 75mm throttle body. I will probably be ordering my BBK 75mm throttle body and plenum this week and was wondering what is the difference. They both cost about the same so i see no point to the 70mm unless you get different gas mieage or something like that. Thanks in advanced.

Everyone says that unless you're going to run forced induction on your car, stick w/ the 70mm. But I'm running the 75mm TB/Plenum setup on my N/A GT and the power gains were good enough for me. So I say go w/ whatever your bank account or preference takes you...
