Air induction is an emissions thing. Its purpose is to complete the exhaust burn, AFTER the exhaust valve. It raises the exhaust pipe temp and causes a lean (popping on decel) condition.

Removal will do nothing but lighten (less weight) and stop lean popping. Leaving in place will also do nothing for performance (unless it fails re: vacuum leak at carb).
