I saw one guy running that on his built all motor b18 in illinois last week and he swears by it. I saw some good aspects of it but also trust AEM any day.

my friend mike had it on his mildly built gsr and when he went from his akimoto intake(before the AEM CAI came out) to the prm we could actually feel the high rpms feel like it was holding back, as if it couldnt breathe, then we put the akimoto back on and started to pull hard again.
