Plug and Play Roush Boost a Pump. Had this on my 13 for about 4 months before I upgraded to a fuel system to run E85. Serves it's purpose and is truly plug and play, all you have to do is run the harness to engine bay for the boost sensor. You will need a brass 1/8NPT adaptor to install. They cost like $4 on ebay, or you can buy it from Roush for $33. I'm still using mine for my boost gauge. The $1000+ kit from Roush for the stage 3 upgrade is basically this Boost A Pump along with a pulley and reflash. $300 Shipped (in CONUS)
