Intercooler Piping (UICP/LICP):

The upper intercooler piping (UICP) isn't going to do much in terms of gains but it will limit you to a stock flanged DV/BOV. The lower intercooler pipe is a great mod. It will improve spool up. Reason being, the stock LICP tapers towards the turbo and has unnecessary bends.

- UICP: Not really a necessary mod unless you need a different flange or you are using a mini battery and have the room to use a shorter route UCIP.
- LICP: Definitely a great mod, you'll see HP/TQ gains as well as quicker spool up.
- It's not a bad idea to upgrade the stock pipe couplings. They tend to expand under boost.

i upgraded mine with a "hell why not" mentality as well; i was upgrading the uicp, ic, intake, widemouth o2...so damn, might as well!
