To those people with bar and plate intercoolers, these are the worst type of intercoolers. Tube and fin is better.
You actually get air flowing throught a tube and fin, whereby the air will smack the bar and plate intercooler and rebound back, or up and down, sideways. Waste of time really. So yeah, no matter how large or shiney your bar and plate is, it will always be inferior in performance gain.
do you have a concrete proof to prove this?
