I bought some stuff of Aliexpress (power folding mirrors, CSK/Majesty intercooler) and both work fine. IMO if its something simple (intercooler piping is intercooler piping; intercooler is just tube/fin or bar/plate design with end tanks) they will work fine. My mirrors have worked no issues for the last 3 years, folding in/out everyday.
The issue will be the fitment. The intercooler did not fit perfectly and when putting the old mirror caps onto the new power folding mirror it required some gentle pounding of my fist to make it fit. Not real issues for the price you pay.
Quick search on Amazon and looks like the same generic parts everyone sells. Intercooler piping, boost tap, turbo blanket etc....
