Throttle Body Spacer worth it?


Registered User
I have drawn up a list for stuff to tune my Ko3 to eek more power out of it and while browsing i found Throttle body spacer supposed to give some mid range oomph all the posts that I see on here relate to fitting them with WMI kits something I won't be doing so are they worth it, also the ECS light weight pulleys as well are these a good buy? shopping list so far is
  • Turbo outlet pipe
  • Throttle body pipe
  • Forge I/C hose kit
  • Red Coil Packs (bling)
  • S3 intercooler
