Yea, this intake is trash, I'd be surprised if you don't run into further issues. I don't believe this intake was even engineered for this specific car, so it's likely MAF signal is off, and fuel trims will be trash. There are much better products for these cars, I'd return that asap.
Here's a thread with exactly that info, only pertaining to base (non-si) models though.
