Because of the peaky nature of the B16A2, slapping an intake manifold with shorter runners on it will help make more power where the B16 is comfortable doing so. The Skunk2 and JG manifolds will help shift even more of the area under the curve into the upper RPM range, so you will probably see more peak numbers, but you'll end up losing more torque down low, so depending on what you consider a good power adder, an intake manifold may or may not be what you're looking for.

I'd say a B20 block would be a better investment, but that's just me because I'm an All-Motor ***** .
