I had toyed with the idea a long time ago after hearing about such a thing. Then I couldn't find one anywhere...a few places didn't even know what I was talking about. You can buy an aftermarket throttle body that is larger, you can also get a new throttle "gear" I guess its called, the thing that opens up the throttle body. also you can get an aftermarket intake manifold and fuel rail, etc etc. IMO any of those options, especially all together, would be better than just a spacer...much more expensive, but better. (and easier to find).
