Well the BBK is a 75mm which is too big unless you are going FI soon. The Mac looks as though it isnt polished. If you had to pick from one of the two I would get the MAC and polish it before the install and you will be good. But for all that you could port and polish your stock intake and save $139.99 dollars.

But wouldnt i get bigger Hp gains with a bigger throttle body?

Nope. Thats not the case at all. Youy can ALWAYS get too much air. Its kinda like choking your engine. A 75 will kill velocity unless you have a supercharger or turbo.

In realitly it really doesnt matter which T/B you choose, they really arnt worth much horsepower until you go FI. The only reason I got one was so I had the bolt ons "finished off".

I have seen many a dyno of a t/b (either size) only gaining 2-3 RWHP. If you never plan on going FI it probably would be safer to go with a 70mm, but they are going to be virtually identical.

BTW the BBK is extremely well made and has a very nice fit and finish. I wouldnt buy a MAC, as from everything I have heard they are not quite as well made as most other brands.

i think he is planning on going FI so get the 75mm if you do, i am going with the accufab set up though.
