well u get a cold air intake out of a short ram due to the inner piping on the intake and the foam filter they use plus on the website for them they have pictures of the testing with a normal short ram intake and the secret intake well they did when i bought it at least and it showed much better performance than the normal one.

besides the fact that youll end up paying almost 200 for it, i thought it was worth it... and IMO sounded the best too
