I'm looking at upgrading my intercooler to the Apexi or Greddy. Which one is a better performer? I see Jason has both and the Apexi is a little more but it does include new intakes. Which one is easier to install? I'm pretty mechanically inclined and plan on doing this by myself. There used to be a site with some detailed pics of the Apexi install, but I can't find it anymore. If somebody could give me the site address I would be very appreciative. Thanks for any help. This upgrade will also include the dp, mp and Power FC and maybe new pulleys.
