70mm

Alright so i have a 2004 mustang gt that i think already has a 70mmm throttle body on it but i am thinking about upping it to a 78mm. what else will i have to do to make the switch besides get the 78mm throttle body?

I am looking at buying one of these and have read about the "whine" or whistle sound it makes. I did a search and there appears to be a work around to fix this. I was wondering if anyone has video of the throttle body whine/whistle? Thanks

i was looking at a BBK 70mm for my 97 gt. just a cold air intake on it. how are BBKs compared to Acufab? and will i need a tune for the 70. iv seen people say i do and iv seen some people say i dont.

Leaning towards a PP throttle body due to price, any real difference between 70mm and the 75mm throttle body?

I know there is a specific post where I am supposed to post all the info, but not sure where? Can somone point me in the right direction?

I recently installed a bbk cold air intake with a 70mm throttle body and the plenum combo. I also installed the spacer. So my question is, what MAF meter should I buy and where can I find it??? I have been having trouble finding one for my mustang which is a 2001 gt convertible. Any...
