Haven't bought a DP yet. Looking at IE and APR on high (price) end and Depo Racing (catted) on low end (latter is out of stock right now). I had a Depo Racing FMIC on my Fiesta ST and the quality was good. Also thinking about a Majesty (eBay) intercooler (OE replacement not the FMIC). JB4 install took me longer than most people claim. The lower D plug was a pain. Struggled with it even after removing the lower engine cover...
