The EX intake is more likely to fit, the B16a has a bigger TB so I doubt that will work. However there is more room in the engine bay of EG's so and CAI for that car is very unlikely to fit. You'd have a chance if it were an SRI, but I don't think so unless maybe you cut the pipe and reworked it. Try it, it doesn't take long to test fit intakes.

What do you have on the SI right now?

And yeah, the battery is in a really shitty location, I had to move it in the back of the car just to use the stock intake that came with my motor with a cone filter on it.
