Thanks I will look into both.

 

I got the MAC 75mm t/b and C&L plenum and love it, I did notice some nice gains espically when cruseing on the highway. Check out RPMoutlet.com they have some great combos on the t/b plenumn and CAI. If you are going to get a 75mm t/b defently get the c&l plenum, and if that is what you are going to do save yourself some money and get the Mac t/b over the Accufab, For the price difference even if the Accufab is a little better it is not by that much so I say save yourself the $100 bucks or so and get the Mac. Hope this helps

 

I put on a midpipe, catback, gears and the TB/Plenum on all at once, so it's virtually impossible to tell what effect the TB/Plenum had all by itself. But you can never go wrong with upgrading your throttle body and plenum and Accufab is great stuff. I highly doubt that you will be able to tell the difference between 70mm and 75mm. Maybe if you plan on getting a s/c someday, the 75mm would be a better choice.
