Works as advertised. No whistle and much better performance!

Purchased this shortly after a Volant CAI. Had this installed about a week before the Volant. Did notice a slight difference in ~2500RPM power. Could not state a difference in MPG as I added the Volant shortly after. Interestingly, a Volant tech said this would add about 2HP with minimal gain for MPG.
