im about to order a throttle body and cant decide between 70 or 75 mm. i will not be adding and type of fi since my car is daily driven. i still have the stock intake with the silencer removed and a k&n filter and intake spacer. so my question is will a throttle body be worth it and what size should i go with? thanks

75 is too big for an NA application.

75!!! dont waste you time!, if you go wiht a 70 you will always wish you went with a 75. get a ruler and see what 5mm looks like, its nothing! and not to big for N/A cars....

so will i feel any gains with the stock airbox with the silencer removed or will i just be wasting my time with either throttle body?

If you want to feel a gain you might as well do a TB and plenum.
I use the stock air box in the summer, but an open filter in the winter.

the plenum is cheaper and makes more power, get it first, port your stock tb.. cai mandatory..
