Your right it sounds like a good idea.
But does it have the center post inside the pipe? If it doesn't it will cause an increase of air which the mass air meter can not compensate for. Thus causing the car to run lean. Which then creates pining=detonation. Other than that i have seen them on ebay. But for $16 give it a try. It kinda seems kinda long to put into our cars. But good luck. again.
