This process will remove any excess flashing and smooth the inner surfaces of the intake manifold, thereby reducing turbulance inside the manifold. In theory, u'll see sum gains, probably on the upper end of the powerband. U'll see better gains by ditching the stock airbox for a KKM, Weapon-R, Injen..whatever and by opening up the exhaust side with headers/y-pipe/cat-back. Now I'm just rambling..back to the questions..

Extrude Hone.com, this is where u'll get quotes for the job and where to send yer manifold. It'd be a good idea to buy used/junked manifold to send in, unless you have other transportation while the coug is out of commission.
Later, yo
