Who's numbers? I see plenty of "experts" touting the benefits of the Vararam's "ram air" effect all the time... it's bunk. The Vararam is a CAI like all the others. The benefit comes from unshrouding the intake and ditching the OEM airbox. The simple fact is that the zip-tie mod will get you pretty much the same power as any aftermarket intake.
People love to tout that they gained 3 mph in the 1/4 from the vararam etc. etc. etc. But until I see a back to back test on the same car and same night of stock vs. Vararam it's all BS. I remember the post years ago when the one guy proclaimed his 1/4 mile trap increase and everyone has been spouting the same info over and over and over.
Sure it's an effective CAI, but it's poorly made and it blocks airflow from your engine. If you run any kind of HPDEs you want that air moving over your engine to help remove heat. The Vararam blocks all of that airflow that would normally go over the top of the motor.
