I'd recommend anything but MAC [:'(]. "mm"?

OhThree4.6

like 70mm or 75mm

i dont know what those mean, sizes maybe?

and what brand, accufab, bbk

Well, it depends. If you're keeping the stock airbox, filter, and duct, then 70mm is fine. However, if you're going with a CAI, then you can go 75mm. Also, with the CAI, you could switch the plenum (aka, upper intake). There are several out there. I personally like Accufab TBs and plenums, but they are the most expensive. Skip MAC everything and good luck to you.

the "mm" is the inside diameter of the TB.

Okay, I'm sorry. MM = millimeter. BBK is a good one. Most would recommend 75mm.

You don't need to upgrade to a 75mm throttle body unless you have some type of forced induction. A 70mm accufab will probally be your best bet, unless you have a supercharger, turbo, or forced induction. The you can go up to a 75mm. Othewise the extra 5mm is not gonna do anything for you. I would do the throttle body and plenum combo if I were you (accufab). Good luck!

I was planin on gettin cold air, what throttle body should i get 70mm or 75mm?

or does it matter, im lookin for best perf, there's like a $20 diff

70 mm. A CAI is not forced induction. 75mm will actually probally hurt your performance more then help it. Look I'll make you a chart.

70mm- N/A vehicles with light/medium mods.
75mm- Forced induction vehicles, or heavily modded N/A applications.

Thats ok, you don't need to be sorry. No one knows everything about every car. Thats why you come here and learn. Sometimes I'm just a tad bit scarcastic. Don't take it personal. lol. Good luck!
