The Accufab and Dragon being of higher quality is debatable. if anything, I'd say they were "prettier" to look at since they're cut from a single piece of billet, but that's as far as I'd take it. The usage of Billet aluminum gets beaten to death once too often. Billet is used when strength issues need to be addressed and weight issues are still a concern. Now, every time someone sells something that's been made out of billet aluminum, it’s automatically labeled as a superior product. Billet throttle-body, cast throttle body…ones going to perform as well as another. You pay for the name and a prettier package with the Accufab, but in the end, it's still not moving any more air, or proving any more durable than the BBK.
