Air filter bolts breaking

I bought one of the after market air filters from one of the better suppliers, and I am very happy with it.
The bike breaths much better, but I keep having the 2 little bolts that hold it on snap right where it bolts to the NT carb.
Today I replaced the bolts and broke 3 more of them in 10 minutes of riding!
The bike seems to be running more smoothly than ever before so I can't figure out what could cause them to break so quickly.

I rode around with the stock filter on today for 20 min or so with no breakage. It does not run as well as it does with the after market filter though.

In response to:
In the attached pic, it is showing the short alum intake that I broke. I am about to replace the Long CNS intake with a short Steel intake similar to the one shown.
Dave- It is the filter on the SBP website. The bike runs noticeably better with it on. It is heavier, and when I ran it the other day, I noticed at higher revs it vibrates.
2Door- I have a piece of heater hose between the frame and the brackets. I have heard stories both ways, but as much stuff as I have broken, I am ready to remove those and remout the motor without them.
Bikenut- The filter is in no way contacting the frame. I have tons of clearance on my 27" road bike.
Tommyboy-I am using quality hardware.

I spoke to one of the guys at SBP about my problem and he suggested that I use thread locker on it because maybe the vibration was loosening up the bolts just enough to let them rattle and then stress fracture. I tried this, they still came loose after about 4 miles. I am about to put a smaller intake manifold on the bike. It currently has the CNS super long one, and I think that may be amplifying the vibration.
