The bottom bracket breaking is not an issue of poor welds. Its breaking because of excessive vibration. I "rebuilt" each mount with a 2 inch long bolt, 2 shock absorbor rubbers, and 4 fender washers. Sandwich the bracket between the two rubbers and fender washers, tighten down until the rubbers start to expand. This holds the mount securely, but allows much more flex than the cheap-o rubber mounts supplied with the CAI. I used one of the cheap-o mounts where the filter hanger attaches to the body. So I have three flex points instead of only two.
The cheap-o needs a 1/4-20 nut, flat & lock washer.
I forget the metric size of the threads where the upper mount screws into the coil bracket, I went to Pep Boys with the orginal screw and got a 2 inch long one to replace it with.
The lower CAI mount attaches to a factory hole under the radiator, use a 2 inch 1/4-20 bolt and hardware to make that mount.
So a quick Pep Boys parts list:
4 rubber shock absorbor mounts.
8 fender washers with a 1/4 hole.
3 ea 1/4-20 nuts, flat, lock washers.
1 2 inch 1/4-20 hex head bolt
1 2 inch metric bolt, same size as the one that holds the coil.
I also went to Lowes and replaced the coupler between the two pipes with a heavier 3 inch to 3 inch plumbing connector. It is black just like the 90 bend that comes off the TB, looks much nicer and holds the upper to lower pipe more securely.
I spent about $15 in extra hardware but my intake looks great and mounts much better than if I had used the supplied hardware.
I also bought a short ram intake to be used in winter/spring. I dont want to take any water chances and its cold enough in the winter months that the underhood air will still be plenty cold.
