What we are viewing in the photos is the outlet side of the IC that feeds the throttle body. The inlet side appears to have a tapered feed, but still looks like it has some sharp 90 degree turns on that side as well. You need to reduce the number of sharp turns to reduce the amount of turbulence, which will in turn lower the pressure loss across the IC. The important factor in an IC is the temperature delta over the inlet versus outlet. Pressure delta is important, but I would rather see a improvement in the temp delta's than worry about a 1/2 pound pressure loss.
