Make your EL whistle

[335JET]

Just took the EL for a drive, and i took the air filter out of the airbox just too see if it made much difference in power.
Not only was it quicker but as i was goin through the gears you could hear the air getting sucked through the motor, it had a whistle sound.

However i would not recommened doing this for long periods of time as you dont want too much dirty air goin through the motor.
