Intake is a AEM missing the top lid of it. Also you should get a stock front snorkel to attach to the front of it. Not bad deal though. Paid $25k for mine end of first covid lockdown year.
Is the ayc light on all the time? Mine only came on after driving it for 10 minutes and it will go off after shutting the car off. I already fixed the tail lights and the light never came back
Both are good, I would go with a newer sti if you want more comfort and better features. The evo x is more raw compared to it, but it has cheaper interior etc
