I'm well aware of the difference between a solenoid and the actual wastegate or BOV. Factory techs are trained to look for non OEM stuff, so you are betting against them finding it.
The wastegate solenoid does not look stock, it has rubber hoses now with zip ties. Zip ties on the ends is a dead giveaway. The MAC BOV solenoid does not fit in the original bracket, so it just kind of hangs there, again, that doesn't look stock at all.
Hey, nothing bad against these parts, I just installed mine today, but this is the game you play when you mod a car and this is definitely modding. My main reason for doing it is to smooth out the power delivery. It's jumpy like my old WRX was from the factory.
