Nice work on everything, especially the 3D printing stuff, I had my buddy modify the intercooler grill cover single size recipe out there to 3 different sizes, 2 regular size, 2- 1.5mm longer and 2- 6mm longer for the 3 different lengths going from middle to outside.. your build also looks a LOT like mine, I also have the Eibach's, love how they kill almost all the harshness but still perform really well, and some bright yellow complete housing swap fog lights, but some $70 ones off Amazon, lol... anyway, not sure what direction you plan on going with the intake with the BT coming, but you should wrap the crossover in that heat tape, it sits right over the really hot turbo and crossover and induction hose is where you see gains, air box end is just for sound really.
