Keep in mind these cars sound like crap with open intakes. Its not like the B6 or even B7 cars. with open intakes under part throttle these cars make very audible and very weird groaning noises throughout the time the throttle is pressed. It will sound like the car is broken. It does not sound performance oriented at all.
If you want just the nice blowoff sound, id get a spacer.
Also be advised the K&N intake stretches out the MAF wife to maximum stretch. If you are hard on the car with launches the MAF wire can eventually malfunction. This is a definite design defect on K&N behalf and I brought it to their attention probably 5 years ago now.
This gives you a good representation of it...
