Review on Dorman 03418 Turbocharger Stud Kit by Stephen Pendergrass

Quality is good but did not fit me. They were said to fit the 2008 Mazdaspeed 3 snugly. They were much longer overall (about 20mm), but more importantly, the unthreaded portion of the bolt protruded past the flange of the turbo manifold and downpipe. This will not allow you to fully tighten the nuts as they will simply rest on the unthreaded part. So unfortunately I had to remove them and choose another option.
