i got the new splitter valve on the way and a new boost gauge which should be here soon and i was going to tap into the hose that goes from the DV to the header i think? but it looks old and i wanted to replace it, where should i go? is it just a normal hose or something special?

how do you test to see if you have a leak? I actually want to replace a lot of those hoses to make sure there arent any leaks but if i can test it and just replace the ones i neeed that is easier and cheaper, anyone know the sizes and or brands or watever

 

just go to any auto store and get some hose - bring in a peice of the hose so they can match it.

go to A4mods.com look on the right side of the page towards the bottom and you'll find a boost leak test DIY
