Injen's probably has the diameter and length optimised for the Euro (their current CAI is already the 2nd version). Simota on the other hand just makes the pipe fit the car, but the length and diameter are not optimised.

With CAIs, the heating of the intake air is not too much of an issue as the air sucked in is cold. SRIs on the other hand suck in hot air from the engine bay. In both cases, heat wrap is useless.
