Their fit and finish are much better, but my experience was it took a long time to deliver (ordered Sept 23' received July 24'). Similar when I got the fuel pump holder. They come with o-rings to seal, but since I did a sloppy job boring out my plenum for robZ, some spots would exceed oring placement, I bought CZP TB gaskets to use instead. Mine do stick a little at the closed position when first step on throttle, but maybe I need to adjust open a little more at full close. Since replacing, my idle and drivabilty have been much improved.
