I have heard a lot of good and bad things about replacing the throttle body. Is it worth it to replace it, or would I be alright in just getting a throttle body spacer instead? I know BBK makes both a replacement throttle body at 70mm and I have also seen spacers that also claim to to add some hp to. Would one be better than the other, or maybe both?? Any thoughts?

 

The Helix Power Tower is only around 75 bucks on ebay and claims to get you an extra 4 mpg and some extra hp, might be worth a try?
