It's just the S5 UIM that produces more power on a stock s4. You'll have to try and search it, I'm at my parents and lost my links

You should get a little more hp because of the VDI, BUT the VDI is rpm activated thru the signal from the S5 ECU. You won't have that signal BUT you can either make or buy a rpm switch to activate it. Buy one from SUMMITRACING.com or make one from a JAYCAR KIT at this site http://www1.jaycar.com.au/productView.asp?ID=KC5378

There will be some *fabrication* to make the S5 fit the S4. Do a search on this forum.
