I've never heard of emissions going up drastically with a modified air-intake. I have a BMC CDA kit and my MOT emissions were very very low:

Fast Idle 3000rpm:
CO% 0.003 (permitted range 0-0.200)
HC ppm 1 (permitted range 0-200)
Lambda 1.004 (permitted range 0.970-1.030)

Natural Idle 600rpm
CO% 0.002 (permitted range 0-0.300)
