Even something as simple as this will get the extra intake noise, if that's what you're after. Its as simple as removing the stock airbox and bolting the adapter to the mass air flow sensor in place of the box. For $16 you'll get the same result as somebody who spent $200+ on an Injen or K&N. The only difference is you won't have a shined up piece of pipe.
