I decided to go ahead and give the Stealth A/C a try. The quality, fit and finish is very high. There are however, a few differences from the HD A/C kits, those differences being; the stock breather bolts are not reused during installation, there are no vent tubes connected to the breather bolts (only vent holes and channels molded into the backing plate near the mouth of the TB) and finally, there is an o-ring used to seal the backing plate to the mouth of the TB instead of the paper style gaskets that are typically used in other kits.
