Roush duct gauge's
 

Just woundering anyone has bought them and installed them? Any negitive feed back? Did it cut down on air flow a bunch? Thank you in advance

I don't have it, but was planning on purchasing one after seeing one in a guys car at the gym. He had boost gauge and it looked really clean in the dash. From what I can remember, install wasn't a problem. Not sure about air flow. I'm sure someone will have better info.

Not overly concerened about the install, owning our own shop, it's pretty typical for stuff not to fit.My big concern is loosing air flow. The vents now work great.
