My research back when I was looking for an intake showed the exact opposite. Everyone who was running an intake to their SMIC area was netting gains.

In the end it was simple for me. Ingest hot air from the engine bay, or cooler "outside" air. Does your car run better on a hot summer day, or a cool autumn evening?
